update.mkinfit.RdThis function will return an updated mkinfit object. The fitted degradation model parameters from the old fit are used as starting values for the updated fit. Values specified as 'parms.ini' and/or 'state.ini' will override these starting values.
# S3 method for mkinfit update(object, ..., evaluate = TRUE)
| object | An mkinfit object to be updated |
|---|---|
| ... | Arguments to |
| evaluate | Should the call be evaluated or returned as a call |
