Individual-level survival data for Serengeti and Hwange lions

The structure of the data in datSH.txt by columns is as follows:
1) "id" = individual identifier: sequence from 1 to 4754;
2) "sex" = sex of indvidual: male, female, unknown (m/f/u);
3) "dead" = binary indicator of whether death was confirmed at dissapearance: surely dead? (yes/no);
4) "cens" = censored observation: individual still alive at end of study? (yes/no);
5) "xli" = last seen age of individual i in years;
6) "xti" = left-truncation age of individual i (i.e. “first seen”) in years;
7) "loc" = location: observation from Serengeti or Hwange (s/h);
8) "potEm" = potential emigrant: characteristics of individual at last seen age indicate that the indivdiual may have dispersed (yes/no);
9) "im" = immigrant: individual immigrated into the study area (yes/no);
10) "unsex" = unsexed: did the indvidual die before sex was determined? (yes/no);
11) "outMigr" = out-migrant: expert opinion on whether individual may have dispersed (yes/no), only relevant for Serengeti data.

Note that for the binary indicators 1 indicates "yes", 0 indicates "no".

Data are based on mark-resighting records of the Hwange and Serengeti lion population, respectively. For details on the data collection protocol, please see the "Materials and methods" section in the associated paper.
