Release Notes for BlueSky Statistics 6.20

Application improvements
==========================
1) Made improvements to data entry into a new dataset(blank). The arrow keys allow you to move between cells like Excel. Hitting the Enter key moves to the cell below so that you can enter values.

2) We always preserve the order of the variables in the source variable list on drag and drop. The order matches the order of variables in the dataset.

3) Comments/notes can be added to the analysis in the Output window. Clicking on the note icon above the analysis allows you to add notes. These notes are persisted when the output is saved.

4) You can delete the output associated with the analysis by clicking on the new trash bin icon displayed at the beginning of the output associated with the analysis.

5) Support copy and paste of datasets from Excel or tables from the Windows clipboard into the BlueSky Statistics datagrid. You must click the paste available from the File menu on the datagrid window or the paste available when you right click on the datagrid.

6) We have made the following Improvements -
- Added a new icon to show/hide the output navigation tree. This is available on the top left of the output window. The output navigation tree allows you easily navigate the results of the analysis in the output window. This is useful when there is a large volume of analysis generated in the output window.
- In the navigation tree, if the parent node of an analysis is clicked then the analysis output is scrolled to bring the title of the analysis in the visible area of the output window.
- You can right click on a node in the navigation tree and delete that node and the related data from the output navigation window.
- Provided a selection combobox in output navigation panel that allows you to filter the items displayed in the output window.
- 'Default' selection mode option was not working correctly. It is now fixed.
- The title of the analysis in the navigation tree is renamed to "Title" (earlier we called it "Header").
- In place of "Dataset" we now display "Dataset Name" in the navigation tree.
- In the navigation tree, in place of "Command" for R syntax we now show a part of the syntax that was executed.
- Different icons were implemented in navigation tree for Title, Notes, Dataset name, R Syntax, Tables, Graphics.

7) Output viewer has been updated to show the navigation tree as available in the output window. The show/hide navigation icon is available on the top left of the Output window.

8) The data grid window has been improved to support the directional arrow keys.

9) When you open a dataset in BlueSky Statistics we would create a R data frame object that we would sequentially increment e.g Dataset1, DAtaset2, Dataset3. We have now changed this we now create a R data frame object with the name of the file you are opening. So if you open a dataset called "Cars.csv" the R data frame object will be called "Cars.csv". If you open up an Excel file called "Cars.xlsx" it will be called "Cars.xlsx". If there are spaces, underscores or special characters in the name of the file then we put a period(.) in its place while generating a R data frame name. If the filename begins with numbers then we prefix the R data frame object with a letter "D".


10) If you open a Dataset that is already open, we will refresh and bring focus to that dataset in the UI datagrid.

11) When you open a BlueSky Statistics dialog, that dialog retain focus and stays on top of all the windows. you must click "Ok" or "Cancel" to continue using the application.

12) New output window can be opened using File -> New -> New Output Window

13) Saved output file can be opened using File -> Open Output

Analysis and Modeling
=====================
1) Added support for basic mixed models under top level menu Model Fitting->Mixed Models. We current support a single nesting unit. We will be adding additional capabilities in upcoming releases.

2) Better scoring support for multinomial logistic and ordinal regression models.

3) Multi-way crosstabs displays odds ratio.

4) Added a configuration setting ("Show actual p-values (e.g. p-value=.0002) in the output instead of '<.001***' ") for displaying actual p-values. NOTE: The default setting is unchecked.

5) Updated the version of R we use to R 3.6.1 (NOTE: R 3.6.1 requires .NET 4.6.1, you will require this version of .NET or above)

6) Correlation is new sub menu under Analysis

7) The following dialogs have been updated:
-Make Predictions (The required field indicator was not aligned)
-Principal Component Analysis (PCA) Dialog has explanatory text added 
-Ordinal Regression Dialog has explanatory text added 

8) Added the following new datasets to the "BlueSky Statistics\Sample datasets and Demos\Model Fitting and Scoring folder"
iris.rdata for multinomial regression
titanic test and training datasets for logistic regression
Housing dataset for ordinal regression


Defect Fixes
==============
1) In Multi-Variable One Sample T-Test, fixed an issue with summary statistics not getting displayed for one level of a factor variable.

2) Issue related to the manually expanding/shrinking the output window with the mouse. Instead of resizing the output window it resized the BlueSky Statistics R command syntax editor.

3) The BlueSky Statistics application crashed when a user tried to modify and save the default syntax script.

4) Extra asterisk (*) was displayed in Crosstab table title if no layer variable was selected. This is now fixed.

5) The sum of squares table in linear regression was summing the mean square table instead of the sum of square table. This has been fixed.

6) Fixed issue where characters in long column names were getting cut off in the tables that displayed the results of the analysis.

7) When generating syntax for the "Bar Chart" we were forcing as.numeric on

8) Minor syntax fix done to Summary Statistics, Selected Variables dialog.

9) The setting contrasts was not working correctly we have introduced new dialogs for setting contrasts.

10) Distribution dialogs will work even if the empty dataset is open(or active). For other dialogs an appropriate message is shown.


Dialog Builder 
==============
1) The default increment for spinner control in dialog editor has been set to 1.

2) Checking for duplicate names now works for the spinner controls and the required field indicator.

3) Fixed dialog editor to allow you to define rules that disables the following controls. 
-Slider control
-Advanced slider control 
-Spinner control

4) Fix the issue with saving the R source code script files to a network share.

5) Fixed dialog editor to allow you to define rules that disables the following controls. 
-Slider control
-Advanced slider control 
-Spinner control
