Appendix 1: Guidance for population model construction from Inferring forest fate from demographic data: from vital rates to population dynamic models NeedhamJessica MerowCory Chang-YangChia-Hao CaswellHal M. McMahonSean 2018 Notes on how to construct an Integral Projection Model using the vec-permutation approach. We offer advice on the number of size bins and growth distributions to use, as well as brief notes on correcting measurement error in the data. We present results from sensitivity analyses to matrix size and transition probabilities between growth distributions.
