Adjusted Pearson residuals in beta regression models
Abstract:In this paper, matrix formulae of order n?1, where n is the sample size, for the first two moments of Pearson residuals are obtained in beta regression models. Adjusted Pearson residuals are also obtained, having, to this order, expected value zero and variance one. Monte Carlo simulation results are presented illustrating the behaviour of both adjusted and unadjusted residuals.
Keywords:adjusted Pearson residual  beta distribution  bias correction  normality test  Pearson residual
