Extract model parameters from mkinfit models

This function always returns degradation model parameters as well as error -model parameters, in order to avoid working with a fitted model without -considering the error structure that was assumed for the fit.

This function returns degradation model parameters as well as error +model parameters per default, in order to avoid working with a fitted model +without considering the error structure that was assumed for the fit.

object	A fitted model object. Methods are implemented for -`mkinfit()` objects and for `mmkin()` objects.
...	Not used
transformed	Should the parameters be returned -as used internally during the optimisation?

Value

errparms

Should the error model parameters be returned +in addition to the degradation parameters?

For mkinfit objects, a numeric vector of fitted model parameters. -For mmkin row objects, a matrix with the parameters with a -row for each dataset. If the mmkin object has more than one row, a list of -such matrices is returned.

Value

+ -
