Function to create a btfit object

btfit

Fits the Bradley-Terry model

Functions taking a `btfit` object

Functions and methods for a btfit object

summary

Summarizing Bradley-Terry Fits

coef

Extract coefficients of a 'btfit' object

vcov

Calculate variance-covariance matrix for a btfit object

fitted

Fitted Method for "btfit"

btprob

Calculates Bradley-Terry probabilities

simulate_BT simulate

This function simulates one or more pseudo-random datasets from a specified Bradley-Terry model. Counts are simulated from independent binomial distributions, with the binomial probabilities and totals specified through the function arguments.
