Hi, my name is Todd Swannack and I am a PhD student at Texas A & M University. I am working with some of my mark-recap data on Houston toads and I have a question or two about the design matrix. I have been working my way through ‘A Gentle Introduction’ want to make sure I am on the right track.
I have one group and have run the CJS model. I would like to test a model with a covariate (precipitation) while keeping recapture probability constant. I have set up my design matrix as follows:
B1 _ B2 _ Parm _ Pint
1 _ 41.49 _ 1:Phi _ 0
1 _ 44.56 _ 2:Phi _ 0
1 _ 45.27 _ 3:Phi _ 0
1 _ 26.41 _ 4:Phi _ 0
0 _ 0 _ 5:p _ 1
0 _ 0 _ 6:p _ 1
0 _ 0 _ 7:p _ 1
0 _ 0 _ 8:p _ 1
My main question is: does this look right?, and if not, does anyone have any suggestions on how to fix it? Thanks for any assistance. I really appreciate it.
Take care,
Todd
