• Sphericity test for RM-ANOVA in Univariate approach

  Hi
  
  As I know it, there is no test to get the Mauchly sphericity test when doing RM-ANOVA in the Univariate approach.  Is there any way to get this, instead of doing the analysis in the MANOVA approach? Since I want to do post-hoc tests in the univariate format directly in the same output. Any add-in or any other approach I easily can investigate sphericity (and, if needed, get the adjusted F-values...

  Is it adequate to do this in the Fit Y by X platform? The response variable of interest on Y, and "Time" (session in my case)) on X? I prefer this way making i...

• A function to add columns with names that has a prefix

    Hi community,   I want to write a function to add columns that have names that has a given prefix, and give values to the columns based on given conditions. This is the script that I have, but it errors out "Unresolved Column". I double checked everything and don't know where went wrong...   Much appreciated for the help!   add_extra_columns = Function({dt, prefix}, {Default Local}, dt << New...
