zim.fit: Fitter Function for Zero-Inflated Models
In ZIM: Zero-Inflated Models (ZIM) for Count Time Series with Excess Zeros

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.

1 2	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 `zim.control`.
`...`	additional argumetns.
