zim.fit
is the basic computing engine called by zim
used to fit
zero-inflated models. This should usually not be used directly unless by experienced users.
zim.fit(y, X, Z, weights = rep(1, nobs), offset = rep(0, nobs), control = zim.control(...), ...)
y | response variable. |
---|---|
X | design matrix for log-linear part. |
Z | design matrix for logistic part. |
weights | an optional vector of 'prior weights' to be used in the fitting process. |
offset | offset variable |
control | control arguments from |
... | additional argumetns. |
