PROC MIANALYZE missing class variable

[jamiemblack]

Hello,

I am trying to run a proc mianalyze on my genmod ouput, but I keep getting an error that I'm missing variables: 

ERROR: Variable APOEn is not in the PARMS= data set.

But when I open up the temporary parms dataset in my Work folder, the variable is APOEn is listed as one of the parameters. 

Any suggestions?

*Note: I had originally tried to get parameter estimates with a ParameterEstimates in the ods output statement, but with no success. I found GEEEmpPEst in another SAS forum, so I'm not sure if that is what is leading to my missing variable error?

Here is my syntax:

ods select none;

proc genmod data=ce.imputed_data2;

class isid depression(ref='0') apoen(ref='0') dementia(ref='0') gender(ref='Män') diabetes(ref='0') cancer(ref='0') heartattack(ref='0') SES(ref='0') educationlevel(ref='0') smokingstatus(ref='0')/param = ref;

model depression=apoen dementia gender BMI diabetes cancer heartattack SES Educationlevel smokingstatus/ covb;

repeatedsubject=isid;

by _Imputation_;

    ods output GEEEmpPEst=gmparms CovB=gmcovb ParmInfo=gmpinfo;

run;

ods select all;

proc mianalyze parms=gmparms covb=gmcovb parminfo=gmpinfo;

class apoen dementia gender diabetes cancer heartattack SES educationlevel smokingstatus;

modeleffects Intercept apoen dementia gender BMI diabetes cancer heartattack SES Educationlevel smokingstatus;

run;

Thank you in advance for the assistance!

I might check to make sure the variable name is APOEN and not the variable Label. If by "open the data set" you mean open in a table view you may be seeing a Label and not the variable name. At least that is a simple thing to check.

Thanks for the response. It wasn't that APOEn wasn't the variable name, I needed to specify a classvar= option for parm=  in the proc mianalyze syntax. I found the more appropriate ods output table name for GEE parameter estimates with model-based standard errors (GEEModPEst), which needed /MODELSE to be added for the repeated statement in proc genmod. I also had to add /dist=bin to the model statement. 

ods select none;

proc genmod data=ce.imputed_data2;

class isid depression(ref='0') apoen(ref='0') dementia(ref='0') gender(ref='Män') diabetes(ref='0') cancer(ref='0') heartattack(ref='0') SES(ref='0') educationlevel(ref='0') smokingstatus(ref='0')/param = ref;

model depression=apoen dementia gender BMI diabetes cancer heartattack SES Educationlevel smokingstatus/dist=bin covb;

repeated subject=isid/MODELSE;

by _Imputation_;

    ods output GEEModPEst=gmparms CovB=gmcovb ParmInfo=gmpinfo;

run;

ods select all;

proc mianalyze parms(classvar=level)=gmparms covb=gmcovb parminfo=gmpinfo;

class apoen dementia gender diabetes cancer heartattack SES educationlevel smokingstatus;

modeleffects Intercept apoen dementia gender BMI diabetes cancer heartattack SES Educationlevel smokingstatus;

run;
