Subject:      Class dicotomous variable in Proc mixed
Content-Type: text/plain; format=flowed

Hello,

I know if I have an independent categorical  variable, say, X, I can use
'class X' before model statement. However, for dicotomous variable, say,
X=0/1 if I use or not use class X, it appears that the output is different.
So how to interpret the difference of estimates and p-value? I am not sure
how SAS handles these differenctly.

Thanks,

Zhu
