lefko3 (version 3.7.0)

Historical and Ahistorical Population Projection Matrix Analysis

Description

Creates matrix population models for use in population ecological analyses. Specializes on the construction of historical matrices, which are 2d matrices comprising 3 consecutive times of demographic information. Estimates both raw and function-based forms of historical and standard ahistorical matrices. It also estimates function-based age-by-stage matrices. Methodology based on Ehrlen (2000) and deVries and Caswell (2018) .
