Unequal Variance Log Normalization

Hi, 

Why is the unequal variance not in log normalized numbers similar to the ANOVA? I want to test if the log normalized standard deviations are similar between my subjects:

Re: Unequal Variance Log Normalization

How did you set up the response in this analysis prior to launching Oneway platform? Is it a data column in the data table? Or did you transform it in the launch dialog?

 

I cannot reproduce the problem you have. Here is :weight by :age (original variables):

Here is the analysis after creating a new response column with a formula:

Both the ANOVA and Unequal Variance use the same transformed data. Here is the result using a virtual formula:

Again, both analyses use the transformed response.
