Northern Yellowstone Elk survival and competing risks

Please refer to the corresponding publication for methods of elk telemetry, determination of cause of mortality, elk age structure, and recovery of wolf-killed elk. Elk telemetry and survival data were processed into the format required by R package Flexsurv for competing risk analysis. Elk have records for each 'elk year' they were observed during the study period (2000–2009, 2011–2016), where 'elk year' runs from June to May. Start and stop times refer to their ages at the beginning and end of each year. The start age is mid-year if they were captured and marked that year, the stop age is at the end of the year unless they died, their collar failed, or they went missing. For elk marked as yearlings, we excluded their yearling year of data. Elk telemetry and survival data were processed into the format required by R package Wild1 for CIF analysis. These elk are the same as those in the other dataset, but the format was changed. Here time refers to days of the year rather than elk age. Please see the README file for additional information.
