Weighted least square estimates of the parameters of a model of survivorship probabilities.
"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."
