weibull_survival

This function calculates the survival rate to reach a specific age using the Weibull function.

Provides tools to calculate the alpha parameter of the Weibull distribution, given beta
and the age-specific fertility of a species, so that the population remains stable and stationary.
Methods are inspired by "Survival profiles from linear models versus Weibull models: Estimating stable
and stationary population structures for Pleistocene large mammals" (Martín-González et al. 2019)
