Hi
Using SAS 9.4, applied mixed model which is posted on example 56.5(Random Coefficients) for triplicate MTT results.
To minimize the difference between batches and get general tendency of concentrations, I used mixed model.
Although I get data from this code, struggling with displaying the graph or plot.
Is there a code which I can use for displaying plot?
Follwoing is the code I used(SAS guide mixed model example 56.5)
data rc;
input Batch Month @@;
Monthc = Month;
do i = 1 to 6;
input Y @@;
output;
end;

See what you get with:
