Currrntly I'm doing masters thesis on migration using count model.poisson and neg.binomial have no problem but when i try zeroinflated and hurdle model some pridctor variable shows error in r software.....like computationally singular
So how I can fix the problem and include the variable in analysis???
Group C is a control group. No surgeries to the group but sampled as the other 3 groups that had different techniques of a rumenotomy procedure. Each group had 3 males and 3 females as sub group. Sampling were before surgery as PRE,then postsurgeries as 0hr, 5hrs, 24hrs,48hrs, 72hrs, weeks 1,2 and 3. How do I compare the groups. I'm using graphpad prism 5.
Assays were for Cytokines.
