Performs approximate conditional inference.
a fitted model object. Families supported are binomial and
Poisson with canonical link function (class
the covariate occurring in the model formula whose coefficient
represents the parameter of interest. May be numerical or a
two-level factor. In case of a two-level factor, it must be
coded by contrasts and not appear as two dummy variables in the
model. Can also be a call to a mathematical function (such as

This function is generic (see
functions can be written to handle specific classes of data.
Classes which already have methods for this function include:
The returned value is an approximate conditional inference
