Everywhere, individuals who are selected into one group, will likely be different from the characteristics of individuals in other groups. This selection problem is the core problem that must be considered. As this selection process occurs, this is a very important factor to be observed. Ignoring the non- random selection will lead to selection bias, either on the basis of observed or unobservable characteristics which will be the focus of this study. Sample selection models have been widely used in various fields since the introduction of a two step estimator called Heckmanโs Two Step Estimator. However, this model is only concern on the participant, either in parametric, semi- parametric and non-parametric sample selection models. Hence, in this study, parametric and semi-parametric sample selection models are proposed. Instead of the participant as in previous models, the proposed models focus on non-participant for both parametric and semi-parametric of sample selection models.Item Integration model in life premium tables of family takaful [electronic resource](Terengganu: Universiti Malaysia Terengganu, 2013-01) Puspa Liza GhazaliInsurance or Takaful in Islam means "guaranteeing each other".
