The final release of statistiXL Version 1.7 is now available for free download. Changes with this release include:
- statistiXL now provides support for Microsoft Office Excel 2007. This overcomes incompatibilities experienced by Version 1.6, particularly with regards to charting. It also includes the ability to work with the new format larger worksheets of 1048576 rows x 16384 columns.
- Version 1.7 of statistiXL now provides support for Microsoft Windows Vista Operating Systems. statistiXL 1.7 will install and run under Microsoft Windows Vista.
- Support for non-English language versions of Windows and Office has been enhanced. In previous versions of statistiXL, checkbox options on dialog forms were not properly restored between tests. Checkboxes would typically be restored in an indeterminate state (i.e. neither checked or cleared). If not manually corrected for each test this would lead to unexpected errors when attempting to perform an analysis. Checkbox settings are now remembered and restored correctly between tests when running statistiXL on non-English versions of Excel and Windows.
- The ability to add Prediction Bands to bivariate regression plots has been added. This supplements the Confidence and Standard Error Bands available in previous version of statistiXL.
- Multiple Linear Regression now tests for Multicollinearity between variables. Variables with a Tolerance of 0, indicating exact multicollinearity, are automatically excluded from the analysis.
- Cluster Analysis now behaves like other tests, outputing results to a new blank worksheet when the Output Range field is left blank.
