Fits Bradley--Terry model, also known as a quasi-symmetry model, to paired comparison data via maximum (quasi) likelihood estimation.
BradleyTerry(C, family = stats::quasibinomial)
| C | a square matrix of paired comparisons |
|---|---|
| family | a description of the error distribution and link function to be used. See |
An object of class "glm"
This implementation avoids calling BradleyTerry2::BTm() and
instead fits the glm directly.
By default, the model is fitted by quasi-likelihood (allowing non-integer counts) with a logit link.
To fit by maximum likelihood instead, set the family argument to binomial.
