I am doing a permutation test and i have gone as far as getting difference of the means using proc ttest. My next step is proc iml and thats where am stuck.
i keep getting the following error message on the log:
106 ods output off;
What am i doing wrong?
thanks
Fix your errors in the order they come, since errors cascade.
WARNING: Variable cash excluded because of type mismatch with x.
Fix this first, likely the variable 'cash' is character when it should be numeric.
No "cash" is numeric. and school is a character variable.
Post the actual code you're referencing. Make sure it runs with their data and then switch to your data.
*borrowed code from internet ... randomizes observations and creates a matrix ... one row per randomization ;
proc iml;
use pocketcash; * change data set name here to match your data set name above;
read all var{school cash} into x; *change varibale names here ... make sure it is class then var ... in that order.;
p = t(ranperm(X[,2],1000)); *Note that the "1000" here is the number of permutations. ;
paf = x[,1]||p;
create newds from paf;
append from paf;
quit;
Not sure why its posting with the breaks but i hope it makes sence to you,
