Nothing
The implemented method uses for smoothing bivariate thin plate splines, bivariate lassotype regularization, and allows for both period and cohort effects. Thus the mortality rates are modelled as the sum of four components: a smooth bivariate function of age and time, smooth onedimensional cohort effects, smooth onedimensional period effects and random errors.
