Summary

The dataset consists of two csv files one for adult snakes and one for captive-reared juvenile snakes. The data contains start times (when snakes entered the study) and end times (when snakes died or were censored from the study) for survival analysis. The data also contains general information about the individual snakes (id, snout-vent length, treatment group, whether or not they were translocated), sex (juveniles only since adults were all female), surface activity (and data needed to calculate surface activity), and average distance moved between telemetry resighting. The above information was used as covariates in the survival models. These data support the following publication: Nguyen, A.M., Todd, B.D. and Halstead, B.J., [...]

Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

Purpose

The data was collected to estimate the probability of survival for different treatment groups of adult and juvenile snakes. The data is appropriate for survival analysis using Kaplan-Meier survival curves and Cox Proportional Hazard models.
