Good morning all,
I have begun to analyze my data collected from four sampling events (Aug, Oct, Mar, Apr). I have 3 site covariates and four sampling covariates. My models are giving me high SE (6+ figures) and some are giving an error (-1.#IND00). I have not had this happen before and am not sure how to interpret the output. The model holding occupancy and detection constant or the models holding one or the other constant are the ones with high SE and the models with site and sample covariates have SE's within a more normal range. I am unsure if my high SE is an indication of the real parameter has approached the upper limit or sparse data. In my first two sampling seasons I did not detect any mudpuppies. However, in the 3rd sampling period (March) I caught mudpuppies at 13 of the 20 sites and then the fourth sampling season I caught mudpuppies at 4 sites. We know these are temperature driven from previous studies. The females in March were all gravid and in the April sampling period I only caught males so the females had laid eggs and were nest guarding. However, it does give my a lot of zeros. I can share my data and models. Any feedback would be greatly appreciated.
