Wald Test for Categorical Variables

Post by vivian1234 »

Hi,

I'm using R2MLwiN to fit multilevel model for my continuous outcome variable. Is there any way to perform Wald Test for categorical variables? I know it is possible to use MLwiN software to perform Wald Test, but I can't find any information from the article in the Journal of Statistical Software.

Thanks a lot.

Vivian

The linearHypothesis function from the car library should provide the same functionality as the Intervals and Tests window in MLwiN. For an example of using it see the beginning of the User Guide chapter 9 replication materials (http://www.bristol.ac.uk/cmm/media/r2ml ... ide09.Rout).
