I am working on a clinical trial where I have to count the updated allocation of each treatments. There are 3 treatments(T)(1,2,3) and 3 age factors(J)(1,2,3). The current data set looks like this:
Subject T J
1 3 1
2 2 2
3 1 3
4 5 1
5 2 3
2310 1 3
If J=1 and T=1 are equal to each other then Z11(variable for allocation) increases by 1
If J=1 and T=2 then Z12 count remains the same.
if J=1 and T=3 then Z13 count remains the same.
The above condition repeats for when J=2 and when J=3. And iterates each time a subject is added into the trial.
So basically Zjt=count+1 if T=J and Zjt=count if T is not equal to Z.
The dataset Z should look something like this
Z11 Z12 Z13 Z21 Z22 Z23 Z31 Z32 Z33
6 1 4 7 5 9 10 15 12
I wrote the code below but it does not give me the result I want
array a z11-z13;
do i=1 to dim(a);
if t=1 and fac1=1 then z11=count+1;
else if t=2 and fac1=1 then z12=count;
else if t=3 and fac1=1 then z13=count;
Thank you for any help at all.
