Analysis Bug Fixes

  • Fixed the issue in which Multiple Logistic Regression analysis results were incorrectly updated upon changing categorical Negative and Positive outcome values in the parameters dialog
  • Fixed the issue in which Prism would crash while attempting to perform Nonlinear Regression with an implicit equation with no constraint for one of the parameters
  • Fixed the issue in which the profile likelihood CI was incorrectly calculated for some models of the Nonlinear Regression analysis
  • Fixed the issue in which Multiple Logistic Regression results were incorrectly updated after changing data for the dependent (outcome) categorical variable
  • Fixed the issue in which results of the "Smooth, Differentiate, or Integrate Curve" analysis were incorrect when the source data contained missing Y values
  • Fixed the issue in which the alert "This file was created by a new version of Prism" appeared in Prism 8 upon opening a Prism 9 project with t-test analysis results which did not contain an Estimation Plot
  • Fixed the issue in which Prism would freeze while attempting to perform Nonlinear Regression with options to identify "unstable" parameters and an equation containing the "beta(j,k)" function
  • Fixed the issue in which the floating note "The model has changed. Please, re-define" did not appear in the Multiple Linear and Logistic Regression results if variables used in the model were deleted from the input data
  • Fixed the issue in which "β0=(Undefined)" VIF constant of the Multiple Logistic Regression analysis was wrongly reported in the Hook constant dialog
  • Fixed the issue in which Prism would crash when attempting to perform Multiple linear regression with 1023 interactions without an intercept term
  • (Win) Fixed the issue in which it was impossible to switch to the results of Multiple logistic regression after changing variable types in the source data table
  • (Win) Fixed the issue in which incorrect level names appeared in the "Negative/Positive" Outcomes dropdown menus in the Multiple Logistic Regression parameters dialog
  • (Win) Fixed the issue in which the yellow iteration window did not appear when attempting to perform Multiple Logistic Regression for categorical variables with a huge number of levels
  • (Mac) Fixed the issue in which it was possible to select the same value for both the Positive and Negative Outcome in the Multiple Logistic Regression parameters dialog
  • (Mac) Fixed the issue in which the "Recalculate automatic reference levels" checkbox was unexpectedly enabled in the Reference Level tab of the Multiple Linear Regression parameters dialog if the "Define reference level" section was empty
  • (Mac) Fixed the issue in which the text string "Unpaired (two-sample t-test)" unexpectedly appeared in the "Parameters: Multiple t tests" dialog when selecting an Unpaired Experimental Design and the option for "nonparametric" under "Assume Gaussian distribution?"
  • (Mac) Updated Prism to automatically select the first two data sets for the "Multiple t tests" analysis invoked via the analysis toolbar button from a data table with three or more data set

Other Bug Fixes

  • (Mac) Added "Save a Copy" and "Rename This File" items to the list of Save commands on the main toolbar
  • (Mac) Fixed the crash that occurred when opening a Prism document containing a grouped bar graph with a vertical separating line generated from an analysis
  • (Mac) Fixed a rare crash that occurred when opening a Prism project containing certain pairwise comparison lines on a graph
  • (Mac) Fixed the issue in which the "Format Graph" and "Pairwise Comparisons" buttons on the toolbar unexpectedly appeared inactive (dimmed) for residual graphs
  • (Mac) Fixed the issue in which the "Delete Sheet(s)" dialog appeared instead of the "Delete all [ ] sheets in the family?" error message after clicking on the "Family" folder and pressing the Delete key on the keyboard
  • (Mac) [macOS Big Sur] Fixed the issue in which the "Order" column title on the "Reference Level" tab of the "Parameters: Multiple Logistic Regression" dialog was clipped
  • (Mac) Fixed the typo in the Connecting Line Options tab of the Format Graph dialog for multiple variables graphs
