+ calculated using dnorm, i.e. assuming normal distribution.

The total number of estimated parameters returned with the value + of the likelihood is calculated as the sum of fitted degradation + model parameters and the fitted error model parameters.

For the case of unweighted least squares fitting, we calculate one + constant standard deviation from the residuals using sd + and add one to the number of fitted degradation model parameters.

+

For the case of manual weighting, we use the weight given for each + observation as standard deviation in calculating its likelihood.

In the case of iterative reweighting, the variances obtained by this + procedure are used in the likelihood calculations, and the number of + estimated parameters is obtained by the number of degradation model + parameters plus the number of variance model parameters, i.e. the number of + observed variables if the reweighting method is "obs", and two if the + reweighting method is "tc".
