%CIF macro

GS2 — Thu, 01 Oct 2020 13:30:41 GMT

Using SAS 9.4

I am attempting to run the %CIF macro running the following code:

options mprint;

%CIF (data= check,out= CIF, time= TT_censor_date, status= binary_amputation, group=binary_gender, event=1);

TT_censor_date is a numeric variable

binary_amputation is 1/0 numeric variable (0 indicates no amp)

binary_gender 1/0 numeric variable (0 indicates male)

Below is an example of the variables I am using from my data set:

data have;
input id tt_censor_date binary_amputation binary_gender;
datalines;
1 8 1 0
2 50 0 1
3 100 1 1
4 200 0 0
5 679 1 0
;
run;

when I run the macro I get the following error in the log:
