Individual weighted residuals

Web6 jan. 2024 · Basic goodness-of-fit plots, individual weighted residuals (IWRES), normalized prediction distribution errors (NPDE) over time and visual predictive checks (VPC) were used to assess the model. A bootstrap resampling method was used to evaluate the stability of the final model and the precision of parameter estimates . WebWeighted least squares ( WLS ), also known as weighted linear regression, [1] [2] is a generalization of ordinary least squares and linear regression in which knowledge of the variance of observations is incorporated into the regression. WLS is also a specialization of generalized least squares . Introduction [ edit]
