Age-by-maternal-age Markov chain with rewards analysis of variance in LRO in rotifers

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).
