one of "identity", "probit" and "logit" to fit
respectively the linear probability, the probit and the logit
model
method
"ml" for maximum likelihood (the only relevant
method for a regression without instrumental variables),
"twosteps" for two-steps estimator, "minchisq" for minimum
chi-squared estimator and "test" to get the exogeneity test,
start
a vector of starting values
robust
only when method = "twosteps", should the robust
covariance matrix be computed?
opt
optimization method
maxit
maximum number of iterations
trace
printing of intermediate result
check_gradient
if TRUE the numeric gradient and hessian
are computed and compared to the analytical gradient and
hessian
...
further arguments
object, x, type
a binomreg object and the type of residuals
for the residuals method
