plot_coh_pars

Miscellaneous plotting functions for lca.rh type regression objects. Plot of the cohort effects of the generalised Lee-Carter model

Description

This function plots the age- and time-specific patterns of the cohort effects (only) obtained from the fitting of a generalised Lee-Carter model.

Usage

plot_coh_pars(lca.obj)

Arguments

lca.obj

an object of class lca.rh (containing a generalised LC model with a cohort effect)

Value

A plot with two graphical regions showing the age- and time-specific cohort parameters (i.e. beta_x^{(0)} and iota_t).
