The following is an overview of the new features in Release 8.9. 

New Homogeneity of Variance data analysis tool

A new Homogeneity of Variances data analysis tool has been added to the Desc tab of the main menu. This tool provides access to the three versions of Levene’s test (including the Brown-Forsythe test), O’Brien’s test, Bartlett’s test, Conover’s test, Fligner-Killeen’s test, the standard F-test, and the Siegel-Tukey test.
.
Rank-serial correlation effect size
.
An option has been added to the T Test and Nonparametric Equivalents data analysis tool for the Non-parametric option (i.e. the ) to use the rank-serial correlation as the effect size for the Mann-Whitney and Signed-Ranks tests.
.
Deming Regression change
.
The degrees of freedom value used in the Deming Regression data analysis tool has been changed from df = n-1 to n-2. 
.
Data Table-like Functions
.
Excel provides a Data Table capability as one of its What-If Analysis tools. This capability allows you to see how changes to one or two variables affect the output from formulas in a spreadsheet. When this facility is used, Excel places a pseudo-function TABLE on the spreadsheet.
.
This release of the Real Statistics software duplicates much of this functionality using the new EVALX and EVALXY worksheet functions: Unlike the TABLE “function”, these are real worksheet functions that can be used just like any other Excel array function. EVALX is used for data tables in one variable and EVALXY is used for data tables in two variables.
.
In addition, a new EVAL2 worksheet function has been added that provides similar functionality to EVALXY except that only one function value is computed, and not a table. All three of these new worksheet functions use Real Statistics’ lambda capability.
.
Bug-fix
.
A bug in the Multiple Imputation data analysis tool has been fixed which caused the tool to terminate before it displayed all its output.

  1. Hello Dr. Zaiontz,
    Did you have the time to deal with the revision of the determination of the prediction intervals in Deming regression?
