Description
Calculate stage-specific survival
Based on Bill Morris' methods for calculating vital rates, available on the Wiki.
Usage

stage_specific_survival(b, adult_definition = "median",
census_start_month = NULL)
Arguments
b
Name of the tbl_df containing biography data generated by the function read_bio_table.
adult_definition
How adult females are defined in terms of age at first birth. Options are "median" or "minimum".
census_start_month
A vector of start months for each study. Should be same length as the number of studies. Defaults to January.
Value
Output is a tbl_df that includes the probability of survival for each life-history stage for each study species. Life history stages include newborns, juveniles, and adults; these are defined as in Morris et al. 2011. Also included are the number of animals and the "animal-years" of observation on which the calculation is based.
Examples
