PLease help correct this, I wish to do it by replicates.
This is the code. The data set and error message is below.
CODE
proc iml;
use Complete_1;
read all var _all_ into DM;
close;
frequency =DM[,7]; y =DM[,6]; obs=DM[,10]; Censored= DM[,4]; time = DM[,3]; x =DM[,2];replicate=DM[,1];
use GIB_&p;
read all var _all_ into Col;
timeS=time;
locC=loc(censored=1); matrix=J(1,7,2.10);
do im = 1 to 1;
u = unique(Replicate);
byIdx = loc(replicate=u[im]); /* the UNIQUE-LOC trick */
byGroup = DM[byIdx,];
frequency =byGroup[,7]; y =byGroupDM[,6]; obs=byGroup[,5]; Censored= byGroup[,4]; time = byGroup[,3]; x =byGroup[,2];replicate=byGroup[,1];
do j= 1 to frequency[1];
seed=-1;
A=RANUNI(-1);
i=max(loc(Col[,j]-A>0));
if i<nrow(time) then /** do nothing if the last is censored, that is censored=1*****/
do;
timeS[locC
end;
end;
sim=repeat(im,nrow(time),1);
temp=obs||censored||time||Y||timeS||X||Sim||replicate;
Matrix=matrix//temp;
end; matrix=matrix[2:nrow(matrix),];
create impute_t_&p var{obs censored time Y timeS X replicate};
append from matrix;
quit;
ods trace on/listing;
proc sort data=impute_t_&p;

The error message
timeS 20 rows 1 col (numeric)
tells you that the timeS vector is longer than the others, so you can't concatenate them together.
