# Release Notes

The changes in each new version of Q are listed below.

## Online Feature Release

October 2020

- Added new menu item Tables - Table of Differences for visualizing differences between two Tables. Statistically significant differences can be highlighted using arrows, cell shading, or boxes.
- A new QScript is available in Modifying Tables or Plots - Update Table Page Names and Titles which allows easier import/export QPacks containing large numbers of tables between Q and Displayr.
- Allow pre-selection of Questions in Modifying Data - Create New Bottom K Category NETs (That is, Bottom K Boxes) and Modifying Data - Create New Top K Category NETs (That is, Top K Boxes). That is, any Questions that are selected before the script is executed will be used to construct the new NETs and no prompts about Questions selection presented. If no Questions are pre-selected then the user is given prompts to select Questions as previously.

## Online Feature Release

September 2020

- The varimax rotation algorithm for Text Analysis - Advanced - Principal Components Analysis (Text) has been modified to perform better with larger data sets. This may result in slight differences in output. Also the return object has been trimmed to have a small memory footprint.
- An update has been made to Text Analysis - Advanced - Create Term Document Matrix so that it accounts for ngrams in the Text Analysis Setup item. The output is now in a sparse matrix format of class
`dgCMatrix`, which is more broadly used than the previous format. - The
**Suggest**feature which provides suggestions for categories in the text coding interface (accessed by right-clicking text variables in the**Variables and Questions Tab**and selecting one of the options under**Insert Variables > Code Text**) now runs faster for larger data sets (over 1000 cases). - The algorithm for the
**Sort by > Similarity to [category]**feature in the text coding interface (accessed by right-clicking text variables in the**Variables and Questions Tab**and selecting one of the options under**Insert Variables > Code Text**) has been updated, which may result in differences in the sorting of cases. - The underlying algorithm for Text Analysis - Automatic Categorization - Unstructured Text, Text_Analysis - Advanced - Principal Components Analysis (Text) and text coding has been modified for better performance. This may result in differences in output such as generated categories, principal components and suggested categorizations.
- The algorithm for categorizing with an existing categorization in Text Analysis - Automatic Categorization - Unstructured Text has been updated. This may result in differences in categorization.
- Text Analysis - Advanced - Setup Text Analysis now shows a page of raw text in the output. The controls
**Page of raw text to show**and**Rows of raw text per page**have been added, allowing the page number and page size to be specified. Previously all the raw text was shown, potentially resulting in an error or unresponsive output for large datasets.

## Online Feature Release

August 2020

- Fix made to Tables - Merge Two Tables and Tables - Merge Two or More Tables, so that merging a text and numeric table does not convert the numeric columns into text.
- The default behavior with unordered categorical variables for Dimension Reduction -- PCA, Scatterplot t-SNE, and MDS -- has changed to not create binary variables. To use the old default with new outputs, simply select the Check Box
**Create binary variables from unordered categories**. - Several features in the R Online Library, including all items in
**Automate > Browse Online Library > Dimension Reduction**,**Regression**,**Segments**, and**Visualization**now use the Value Attributes when converting Pick One and Pick One - Multi questions to numeric values. - Annotations can now be added to the data labels of Visualization - Line Chart based on other statistics in the input table.
- The
**minimum frequency**option for Text Analysis - Advanced - Setup Text Analysis now defaults to scale minimum frequency as a percentage of cases. There is still the option to specify the minimum frequency as a fixed number. - The underlying algorithm for Text Analysis - Automatic Categorization - Unstructured Text, Text_Analysis - Advanced - Principal Components Analysis (Text) and text coding has been modified to perform better with larger data sets. This may result in differences in output such as generated categories, principal components and suggested categorizations.

## Online Feature Release

July 2020

- Visualization - Scatterplot has new option to
**use category labels instead of values**so that row or span labels can be used in the**X coordinates**,**Y coordinates**,**Sizes**or**Colors**variable.

## Online Feature Release

March 2020

- Implemented the dummy variable adjustment technique for missing data in Regression - Linear Regression and the other regression types. It is accessible through the
**Missing data**dropbox for all relevant regression types. - Added
**Output language**control to Text Analysis - Automatic Categorization - Unstructured Text which allows categories and example text in the output to be shown in languages other than English. - Two new QScripts are available in
**Insert > Transform > Modifying Data**: Modifying Data - Create New Top K Category NETs (That is, Top K Boxes) and Modifying Data - Create New Bottom K Category NETs (That is, Bottom K Boxes), which allow for creating new NET categories in*Nominal*and*Nominal - Multi*variable sets.

## Online Feature Release

February 2020

- Regression - Linear Regression and the other six regression types now have an automated outlier removal option. The new input control is called
**Automated Outlier Removal Percentage**and accepts a numeric value between 0 and 50 (including 0 but not 50). If a non-zero value is selected for this option then the regression model is fitted twice. The first regression model uses the entire dataset (after filters have been applied) and identifies the observations that generate the largest residuals. The user specified percent of data values that have the largest residuals are removed from the data. The regression model is refitted on this reduced dataset and output returned. If a zero-value is selected for this input control then no outlier removal is performed and a standard regression output for the entire (filtered) dataset is applied. - More formatting options for secondary data series has been added to Visualization - Column Chart
- Added support for text data in languages other than English in Text Analysis - Automatic Categorization - Unstructured Text through the new
**Source language**control. - Visualization - Scatterplot has been updated so that
*Row/column manipulations*are applied to the input table in the same way as other visualizations when*Input data contains y-values in multiple columns*is selected.

## Online Feature Release

January 2020

- Annotations can now be added to the data labels of Visualization - Bar Chart and Visualization - Column Chart, based on other statistics in the input table.
- Visualization - Scatterplot now able to handle Regression output in the X coordinate and Y coordinate input area. The values in the plot are either the regression coefficients or importance scores respectively depending on the Regression settings.
- Text Analysis - Automatic Categorization - List of Items and Text Analysis - Advanced - Setup Text Analysis now default to counting frequency by number of respondents instead of occurrences in the input text.
- Added Marketing - Price Sensitivity Meter
- In Visualization outputs, the result when multiple
**Row/column manipulation**options are used has been changed.**Number of rows/columns from top/bottom/left/right**is now applied after**Rows/Columns to show**. For example, you can now specify a long list of variables to show using**Columns to show**, and then specify that only the first 3 of the columns selected should be shown, without using an intermediate table. - Visualization - Scatterplot now has the option of adding annotations.

## Online Feature Release

December 2019

- Shapley Regression available for Regression - Linear Regression.
- Tick labels in Scatterplots with categorical axis is now ordered according to the order they appear in input table (instead of alphabetically).

## 5.8.2.0

2019-12-05

- Bug fix.

## Online Feature Release

November 2019

- Raw text replacement and Category replacement options in Text Analysis - Automatic Categorization - List of Items has been replaced by the Required categories (variants can now be specified) and Split into categories option.
- Variant suggestions for Required categories are now shown in the diagnostics output for Text Analysis - Automatic Categorization - List of Items.

- Added Segments - Segment Comparison Table.
- Some some changes in Machine Learning - Deep Learning outputs because of an update to use Tensorflow version 2.0.0

## 5.8.1.0

2019-11-14

- The standard error shown on tables of correlations was computed using (1 - R2)/sqrt(n - 1). This is not correct. It now is computed using sqrt((1-R2)/(n-2)). The statistical tests were using the correct formula, so no change has occurred in terms of which results are flagged as significant.
- On summaries of numeric variables, the standard deviations and associated statistics (standard errors and statistical tests) had an error in them whereby they failed to take missing values into account. If a study has extremely high rates of missing data these may have caused non-trivial differences. This only affected summary tables; not any crosstabs.
- Errors in Independent Complex Samples t-Test / z-Test:
- Column Comparisons report statistically significant differences between values which are identically 100.
- Where the user has chosen to apply a z-Test to test means on this table (
**Edit > Project Options > Customize > Statistical Assumptions > Statistical Tests for categorical and numeric data > Means > z-Test**), but when using the 'alpha' button to test significance the output is providing a link to the t-Test version of the complex samples test for means.

- Bug fixes.

## 5.3.1.0

2018-01-17

- R calculations done in R Outputs are now allowed to continue for up to 1 day.
- Due to changes in the software on which Q is built, the order of rows may change in the following outputs:
- Matched data sets (which will affect results when using Data Fusion).

- The list of subsets in the Homogeneous Subsets section in some significance tests.

- Q now requires .Net 4.5 to be installed.
- Bug fixes

## 5.2.7.0

2018-01-04

- Bug fixes

## 5.2.6.0

2017-12-19

- Bug fixes

## 5.2.5.0

2017-11-13

- Fixed bug where rounding errors can result in the treatment of the median, percentiles and effective sample size to be inconsistent. Based on our sensitivity analysis we have confirmed that this only leads to changes in results in situations where the change is immaterial. In the case of the median, this issue arose on the rare occasion when the median occurred at the middle of two different values. Due to rounding errors, the median was randomly reported as either the higher or lower value, when it should have been the midpoint between the two values. In most cases when this does occur, the two values will be close and the resulting error will be small.
- Other bug fixes

## 5.2.4.0

2017-10-18

- Improve import of MDD data files.

## 5.2.3.0

2017-09-28

- Improve import of MDD data files.
- Other bug fixes

## 5.2.2.0

2017-09-08

- Date variables can display time in charts and tables. Date variables can be aggregated using hours, minutes, seconds or milliseconds.
- Previously when a variable from a Pick Any question only had Missing Data and 1 as values, 1 would not be counted, resulting in 0% shown in the table. 1 is now counted and shown as 100% in the table.
- Q requires .Net 4.5.2 to be fully operational.
- It is now possible to hide tables, charts, R outputs and complete folders from export using
**Hide**from the context menu. - R Outputs returning scalar values and strings are now exported as text to PowerPoint and Word.
- Fixed bug where multiple comparisons correction in Table Options was ignored in Driver Analysis.
- Fixed question naming issues when importing MDD data files.
- Improved looped question detection when importing MDD data files.
- Fixed bug where an incorrect log-likelihood was reported when weights were applied in Segments > Latent Class Analysis.
- Other bug fixes.

## 5.1.2.0

2017-02-10

- Check out the key new features: http://wiki.q-researchsoftware.com/wiki/Q5_Key_Features
- Some menu items have moved or changed names. See here for a list: http://wiki.q-researchsoftware.com/wiki/Changes_to_the_Menus_in_Q5
- Fixed a bug in the scaling of Eigenvalues shown in the technical outputs for the PCA Biplot. This does not change the information shown in the chart or relationships between the points in the chart.
- Formatted the intercepts from Ordered Logit to make them consistent with those from Regression - Ordered Logit, and fixed a bug in the saved probabilities from Ordered Logit.
- Other bug fixes.

## 5.1.1.0

2016-11-18

- Data tables can now be manually entered or pasted in Q via
**Create > Tables > Enter Data**and**Paste Data**, as well as in Standard R items that accept tabular inputs. - Other improvements and bug fixes.

## 5.0.3.0

2016-09-27

- Classifier - Random Forest
- Analysis of Variance - One-Way ANOVA
- Analysis of Variance - One-Way MANOVA
- Fixed bug with Spearman’s Correlation where Spearman ranks were being calculated without omitting the cases with missing values in
*any*of the two input variables. The impact of this bug should be minimal and proportional to the amount of missing values in the data set. We have observed that the bug typically resulted in a difference in the reported Spearman correlation at the 4th decimal place compared to the correct value. As a result, is unlikely that this bug would have affected Spearman correlation significance test results and any inferences made from them. - Improved Qualtrics and Survey Gizmo data file detection
- Fixed a bug where by the word "mean" was appearing in the place of "proportion" in some test outputs.
- Other bug fixes and improvements
