Changing datatype of dataset from unspecified type to specially strutured sas dataset (EST type)

[zfusfeld]

I think the question is pretty self explanatory.

I have a dataset that I need to convert to a specially structured dataset for an analytic procedure I am doing (proc mianalyze). It is currently of an unspecified type, and I need to convert it to an EST type structure. 

I thought it would be a simple datastep, e.g.

data cov1 type=EST;
set cov1;
run;

but this spits out a syntax error. 

Can someone link to a resource on how to manipulate the dataset to be of the EST data structure?

You did not include the ( ) needed when you have dataset options.

Try:

data cov1 (type=EST);
  set cov1;
run;

A minor efficiency note.  You don't have to copy a data set to change its type to EST.  Instead you can modify the metadata for COV1 using PROC DATASETS.

proc datasets lib=work nodetails nolist;
  modify cov1 (type=EST);
quit;

thanks! I also realized i could call the type in the mi analyze procedure a la 

proc mianalyze data=cov1(type=EST);
modeleffects intercept x1 x2 x3;
run;
