This package implements the maximum likelihood methods for deriving Elo scores as published in Foerster, Franz et al. (2016). Chimpanzee females queue but males compete for social status. Scientific Reports 6, 35404, doi:10.1038/srep35404
eloratingopt: main function
eloratingfixed: traditional Elo scores function
elo.model1: internal function for fitting model type 1
elo.model3: internal function for fitting model type 3
elo.m3_lik_vect: vectorized internal function
for fitting mod type 3
Make package more modular, with a more flexible wrapper function.
Option to specify K during burn-in period when fitting only K
Add additional example data
Add additional user control of the optimization procedure, allowing for specification of the burn in period, optimization algorithm, and initial values for optimization.
Add functionality to plot Elo trajectories from within package.
