Student Edition of Statistix 10 Update

06/23/2025 Added the Breusch-Pagan Test to the Results menu for Linear Regression.

 

02/27/2024 Fixed an error in the Scatter Plot Matrix. Some data points didn't appear on the plot for data sets containing omitted cases. Also, the Y-Axis legend was misaligned for plots with only one row variable.

 

06/15/2023 Fixed an error in the Error Bar Chart. The bars in the key on the right side of the chart were out of position.

 

05/29/2022 Fixed an error in the Pareto Chart. The Cumulative Percent curve wasn't always displayed when selected.

 

05/20/2021 Added an option to the results menu to the Proportional Hazards Regression procedure for confidence intervals.

 

03/26/2021 Fixed an error in the Nonlinear Models procedure. The starting values weren't computed correctly for the Morgan-Mercer-Flodin and Richards models.

 

01/23/2021 Fixed an error in Import Excel. Columns of dates were often being imported as real numbers instead of dates. Recall that dates in an Excel spreadsheet must appear in the same format (month/day/year, day/month/year, or year/month/day) as your selection in General Settings.

 

08/28/2019 Added a check box to the Settings | Plot Font dialog box to control whether or not the X-Axis legend on plots can be displayed sideways (vertically) or not.

 

05/29/2019 Added the Stuart-Maxwell Test for Marginal Homogeneity to the McNemar’s Symmetry Test.

 

08/04/2018 Added an option to the Chi-Square Test dialog box to optionally select a Row Label Variable to use to add useful labels to the rows of the chi-square table when using the Table Method. Formally, case numbers where used to label the rows.

 

11/06/2017 Increased the maximum number of dependent variables that can be analyzed at once in analysis of variance from 10 to 20.

 

01/23/2017 Corrected a range check error that occurred when any cell in an empty spreadsheet was double-clicked.

 

01/05/2017 Corrected a range check error that occurred when computing Dunnett's multiple comparisons with a control for a General AOV model including one or more covariates.

 

08/29/2016 Corrected an error in the Transformations Arcsin function.

 

06/29/2016 Added Somers' D and c-statistic to the Logistic Regression and Stepwise Logistic Regression reports.

 

06/17/2016 Added Akaike weights to the Best Subset Regressions report.

 

04/21/2016 Added tolerance intervals to the quality control menu.

 

12/29/2015 Added tests for one variance and two variances to the Hypothesis Tests menu.

 

12/21/2015 The p-value reported for the Folded F Test on the Two-sample T Test report was for a one-sided test. It’s been corrected so that it now reports a p-value for a two-sided test.

 

12/18/2015 The left and right arrow buttons used to move to the previous and next residual plot didn't work properly for analysis of variance models with multiple dependent variables.

 

12/10/2015 Corrected a range check error when using Special Effects for a repeated measures design with only two repeated measures.

 

10/24/2015 Corrected a range check error that sometimes occurred while analyzing an unbalanced repeated measures design.

 

10/16/2015 Added an all-pairwise comparisons procedure to the results menu of the Friedman Two-Way AOV procedure.

 

07/08/2015 Added transformation functions Arccos, Sinh, Cosh, Tanh, Arcsinh, Arccosh, and ArcTanh.

 

03/06/2015 Corrected an integer overflow error that could occur in large data sets with lots of ties.

 

03/04/2015 Corrected an integer overflow error in the Kruskal-Wallis AOV that occurred with large samples.

 

03/03/2015 Added spreadsheet column width control using the mouse.

 

03/02/2015 The number of subjects for each between-subjects level in a repeated measures design are allowed to be unequal. But Statistix would erroneously issue an“empty cells” message when data were unbalanced.
