I am working on a multi-state model with 8 states and 1 environmental covariate. I am working in package marked and the main issue that I am running into is that I am not getting any estimates of error for the parameters (please see below the code for a model that I have run). I would greatly appreciate any help and or direction. Please let me know if more code or context is needed.

- Code: Select all
`#### mod.ss.pt.psiorXs ####`

mod.ss.pt.psiorXs <- crm(pdfh1.proc, ddl = pdfh1.ddl, model = "Mscjs",

model.parameters = list(p=list(formula = ~ time),

S=list(formula = ~ stratum),

Psi=list(formula = ~ or*stratum)),

burnin = 100, iter = 1000, use.admb=TRUE)

mod.ss.pt.psiorXs.real <- predict(mod.ss.pt.psiorXs, ddl = pdfh1.ddl)

mod.ss.pt.psiorXs.real

I should note that "or" stands for open river and it has been added to my design data.

Thank you,

Katie
