[R-sig-ME] dummy variables in hlm

[Shoeayb Qasemi]

 Dear Prof. Bob,

I have run an HLM model that contains an independent categorical variable
(5 categories) at level 2. Four dummy variables entered into the model to
represent the categorical variable. Since the dummy variables all test the
null hypothesis of the categorical variable, do I need to adjust P-values
to control the type-I error rate?

Best,
Shoeayb
