bsw {BSW} | R Documentation |
bsw()
fits a log-binomial model using a modified Newton-type algorithm (BSW algorithm) for solving the maximum likelihood estimation problem under linear inequality constraints.
bsw(formula, data, maxit = 200L)
formula |
An object of class |
data |
A data frame containing the variables in the model. |
maxit |
A positive integer giving the maximum number of iterations. |
An object of S4 class "bsw"
containing the following slots:
call |
An object of class |
formula |
An object of class |
coefficients |
A numeric vector containing the estimated model parameters. |
iter |
