24 January 2008 - Release 3.0.10 Mac and WindowsДЇixed a problem in the X-Y plot for a range of values for Generic F tests. 29 June 2009 - Release 3.1 WindowsДЄdded procedures to analyze the power of tests referring to single correlations based on the tetrachoric model, comparisons of dependent correlations, bivariate linear regression, multiple linear regression based on the random predictor model, logistic regression, and Poisson regression. Re-enabled options dialog for Correlation: Bivariate normal model. 16 December 2009 - Release 3.1 MacДЄdded procedures to analyze the power of tests for single correlations based on the tetrachoric model, comparisons of dependent correlations, bivariate linear regression, multiple linear regression based on the random predictor model, logistic regression, and Poisson regression.

This option has been available for some time in the Windows version (see View menu). The Window menu now contains the option to hide the distributions plot and the protocol section ( Hide distributions & protocol menu item) so that G*Power can be accommodated to small screens. The problem did not occur when the effect size was specified in terms of Two probabilities.

Renamed the Repetitions parameter in repeated measures procedures to Number of measurements (Repetitions was misleading because it incorrectly suggested that the first measurement would not be counted).ДЇixed a problem in the sensitivity analysis of the logistic regression procedure: There was an error if Odds ratio was chosen as the effect size. 5 January 2010 - Release 3.1.2 Mac and Windows Changing the number of covariates now correctly leads to the appropriate change in the denominator degrees of freedom. 22 June 2011 - Release 3.1.3 Mac and WindowsДЇixed a bug in the ANCOVA module.

The problem did not occur with post hoc analyses. 3 July 2012 - Release 3.1.4 Mac and WindowsДЄdded an options dialog to the repeated-measures ANOVA which allows a more flexible specification of effect sizes.ДЇixed a problem in calculating the sample size for Fisher's exact test. The problem did not occur when both sample sizes were identical.ДЇixed a problem in calculating the effect size from variances in the repeated measures ANOVA. 20 August 2012 - Release 3.1.5 Mac and WindowsДЇixed a problem in the test of equality of two variances. The drawers now appear correctly after clicking on the Determine button. 12 September 2012 - Release 3.1.5.1 MacДЇixed a problem with the effect size drawers of ANOVA: Fixed effects. MacДЇixed a problem in FisherвЂ™s exact test.

18 Frebruary 2013 - Release 3.1.6 Mac and WindowsДЇixed a problem in the sensitivity analysis of the logistic regression. 19 April 2013 - Release 3.1.7 Mac and WindowsДЇixed a problem in the exact test of Proportions: Inequality, two independent groups (uncontional). Improvements in the logistic regression module: (1) improved numerical stability (in particular for lognormal distributed covariates) (2) additional validity checks for input parameters (this applies also to the poisson regression module) (3) in sensitivity analyses the handling of cases in which the power does not increase monotonically with effect size is improved: an additional Actual power output field has been added a deviation of this actual power value from the one requested on the input side indicates such cases it is recommended that you check how the power depends on the effect size in the plot window. 31 January 2014 - Release 3.1.8 Mac and Windows Note, however, that the change affects the results only when N is very small. Negative effect directions, that is, slope|H1 = upper limit. 6 February 2019 - Release 3.1.9.4 Mac and WindowsДЇixed a bug in t tests:В Linear bivariate regression: One group, size of slope. 14 January 2020 - Release 3.1.9.5 MacДЇixed a bug that caused the вЂњOptionsвЂќ button (which is available for some tests in the main window) to disappear when вЂњHide distributions & controlвЂќ was selected. 21 February 2020 - Release 3.1.9.6 Mac and WindowsДЇixed a bug in z tests: Generic z test: Analysis: Criterion: Compute alpha: The critical z was calculated incorrectly.ДЇixed a bug in t tests:В Linear bivariate regression: One group, size of slope: |sy/sx|В was sometimes calculated inccorrecty.

Changed the behavior of the вЂњX-Y plot for a range of valuesвЂќ which allowed plotting graphs after changing input parameters in the main windowВ without hitting the вЂњCalculateвЂќ button which, however, is required to update theВ вЂњX-Y plot for a range of valuesвЂќ with theВ new inputВ parametersВ from the main dialog.
