R help - Apr 2010 - general linear hypothesis testing for manova model

Hello,

I have a MANOVA model and I want to test the following hypothesis: LBM 0 where B
is the parameter estimates.

Is there any function to do this in R?

Cheers,

Philippe

Dear Philippe,

The linear.hypothesis() function in the car package should do what you want.

I hope this helps,
 John

Also, at least in many cases, anova.mlm in the base package.

The catch is that the "L" of the LBM==0 has to correspond to a linear
model reduction. The "M" is the transpose of the transformation matrix
(which anova.mlm calls T).
