fitmlogit | R Documentation |
Fits a logistic regression model to multivariate binary responses.

data |
A data frame containing the responses and the explanatory variables. |
mit |
A positive integer: maximum number of iterations. Default: |
ep |
A tolerance used in the algorithm: default |
acc |
A tolerance used in the algorithm: default |
See Evans and Forcina (2011).
LL |
