Dear All,
I am using the pkcorss command to analyse a crossover trial data for the
first time. I rearranged my data to look like the data structure on page 521
of the reference manual (version 7). and when I executed the pkcross command
I received the following error message 'carry not a variable in the data'.
I do not understand this message. Can someone please help explain how I can
set up my data for pkcross to work?
kind regards
