Proc NLMixed with Categorical Variable

APatricio — Sat, 13 Sep 2014 22:39:38 GMT

All,

I understand that proc nlmixed do not have the class statement option. I need help to code a categorical variable Var5 with six levels: Ind_A, Ind_B, Ind_C, Ind_D, Ind_E, Ind_F.

The following is the code which uses 4 explanatory variables:

proc nlmixed data=data;

parms b0=x b1=x b2=x b3=x b4=x

gm1=x gm=x;

w=b0+b1*Var1+b2*Var2+b3*Var3+b4*Var;

ww=w+gm1*t;

consigma=gm2;

model Y~normal(ww,consigma);

random t~normal(0,1) subject=group;

predict ww out= output (keep=Y pred );

run;

The model converges but I need to incorporate the categorical variable.

Any suggestions?

PROC GLMMOD.

proc glmmod data=data outdesign=want;

class var5;

model y=var1 var2 var3 var4 var5;

run;

You'll probably want to go in and rename the variables in the 'want' dataset, as they will be named col1, col2, etc.
