Survival Data for Lophuromy Stanleyi

The data was based on to investigate the survival time of L. stanleyi amidst disappearing natural forest cover following a Capture-Mark-Release (CMR) procedure. The status variable was whether a rodent was recaptured or not [1=Recaptured, 0=Otherwise].
Survival for L. stanleyi were hypothesized to be affected by various factors including habitat type (1=Intact forest, 2=Regenerating forest, and 3=Depleted forest), mean monthly rainfall, breeding status at first capture {1=Not breeding, 2=Breeding], trapping year [1=First year of trapping, 2=Second year of trapping], weight (grams), Sex [0=Female, 1=Male ] and age structure at first capture [1=Juvenile, 2=Adult].
The CMR data were entered in excel, and then exported to STATA for analysis. It was then declared as survival data with time from the first animal encounter in trapping session one to the subsequent encounters in the subsequent trapping sessions as the “time variable”, “status” as the failure variable, and “1(one)” as the failure value.
