Abstract: |
Wild bootstrap estimation hetero-variance linear model is used to establish least square estimation asymptotic distribution of parameters part in hetero-variance linear model.A congruent estimation of covariance matrix of nonhomegeneous variance is given |
Key words: wild bootstrap hetero-variance linear model asymptotic normality |
