What's New in Version 1.2.3
Fixed: App would crash when using X^2 Goodness of Fit and saving the expected values to a new column.
Fixed: F-Test data labels would not change when switching to stacked data.
X^2 Test of Independence:
Editing any of the values, row headers, or column headers of the input values creates a new copy of the values and deselects the current variables. Added a button to save the input value matrix as a CSV file.
Leaving the screen or selecting variables now warns the user that unsaved changes to the modified matrix will be lost and confirms that they want to continue with what they were doing.
