In emvolz-phylodynamics/mlesky: Maximum likelihood estimation of effective population size through time, growth rates, and phylodynamic regressions

mlesky : Maximum likelihood phylodynamic inference

This package performs inference of past population size dynamics from a dated phylogeny using a maximum likelihood approach. The main features are as follows:

• Three different phylodynamic models are implemented (skygrid, skygrowth and skykappa)
• A novel cross-validation approach is used for selecting the smoothing parameter
• The resolution of the grid can be selected using AIC or BIC
• Covariate data can be included into the analysis to quantify association
• Multiple phylogenies can be analysed simultaneously that share the same demographic function

For a complete description of the statistical methodology underpinning this package, see our paper:
