  • Title: Weighted least square estimates of the parameters of a model of survivorship probabilities.
    Author: Mitra S.
    Journal: Janasamkhya; 1987 Jun; 5(1):27-32. PubMed ID: 12281212.
    Abstract:
    "A weighted regression has been fitted to estimate the parameters of a model involving functions of survivorship probability and age. Earlier, the parameters were estimated by the method of ordinary least squares and the results were very encouraging. However, a multiple regression equation passing through the origin has been found appropriate for the present model from statistical consideration. Fortunately, this method, while methodologically more sophisticated, has a slight edge over the former as evidenced by the respective measures of reproducibility in the model and actual life tables selected for this study."
