The performance of a robust multistage estimator in nonlinear regression with heteroscedastic errors
In this article, a robust multistage parameter estimator is proposed for nonlinear regression with heteroscedastic variance, where the residual variances are considered as a general parametric function of predictors. The motivation is based on considering the chi-square distribution for the calculat...
