The update method for the nonprob object with changed arguments or parameters

The update method for the nonprob class object that allows to re-estimate a given model with changed parameter. This is in particular useful if a user would like to change method or estimate standard errors if they were not estimated in the first place.

Usage

# S3 method for class 'nonprob'
update(object, ..., evaluate = TRUE)

Arguments

object: the nonprob class object
...: arguments passed to the nonprob class object
evaluate: If true evaluate the new call else return the call

Value

returns nonprob object

target = ~ single_shift,
svydesign = jvs_svy,
