Description

Class built based on Rogers and castro Models.

Details

The Rogers and Castro models where thought to analize the behaviour of the schedule and to parametrize it. The use is very used in population projections and matematical modelling of migration for behaviour clustering with the persistent regularities and the selectivity in age and sex. The model has four main components (Rogers and Castro, 1981): A single negative curve of the pre-labour force, a left-skewed unimodal curve of the labour force, an almost bell shaped curve of post-labour force. A constant curve c, wich improves the fit of te mathemsatical expression to the observed schedule.
