Hi all
I am needing some help with conducting a closed pop assessment using IELogitNormalMR.
The Setup:
Three primary surveys, each of varying secondary survey length. And each primary survey also varies in terms of Known Marked Animals.
The population between the primary surveys are open, and within the secondary surveys closed (so, in essence we have three closed pop surveys (5 days, 4 days and 4 days) across 14 months.
I have been using the IELogitNormalMR model for the assessment with the following code:
Closed_Proc=process.data(Capensis_Closed,model="IELogitNormalMR", counts=list("Marked Superpopulation"=c(67,67,67,67,67,36,36,36,36,12,12,12,12),"Unmarked seen"=c(67,27,20,28,27,33,36,30,26,20,26,12,8)),time.intervals = c(0,0,0,0,1,0,0,0,1,0,0,0))
Closed.ddl=make.design.data(Closed_Proc)
Capensis_Closed_Mod1=mark(Closed_Proc, Closed.ddl)
I continue getting the following error:
Warning messages:
1: In data.frame(estimate = as.numeric(x$estimate), se = as.numeric(x$se), :
NAs introduced by coercion
2: In data.frame(estimate = as.numeric(x$estimate), se = as.numeric(x$se), :
NAs introduced by coercion
3: In data.frame(estimate = as.numeric(x$estimate), se = as.numeric(x$se), :
NAs introduced by coercion
An example of what my data looks like:
