This set of data and code files is a supplement to the American Naturalist paper:
van Daalen et al. 2021 The contributions of maternal age heterogeneity to variance in lifetime reproductive output
It provides the user the matrices (as first presented in Hernandez et al., 2020, PNAS) and the code to reproduce our analysis or apply the methods to their own data. Two multistate, age-by-maternal-age matrices with basic demographic information (survival and transitions, and fertility) are provided, as well as data to paramaterize a reward matrix. The code presents a Markov chain with rewards approach to calculating mean and variance in lifetime reproductive output from a multistate matrix model, and a method to decompose variance into contributions by individual heterogeneity (from maternal age) and stochasticity (due to inherent randomness in the outcomes of age-specific survival probabilities and age-specific reproductive output).
