interpol_surv: Interpolate yearly survivorship

In courtiol/SileR: Survival Analysis of Elephants Using an Extension of the William Siler's Framework

Description

This function is called internally by other functions. It interpolates yearly survivorship probabilities. The method is described in Slud 2001.

Usage

interpol_surv(death_prob, ages, steps = 10)

Arguments

death_prob	A vector of yearly probabilities of death
ages	A vector of ages for which to perform the interpolation
steps	An integer giving the number of increments for the interpolation (within each year)

Value

A data frame containing the interpolated survivorship probabilities for each age.
