Pearson Residuals

After fitting a generalized linear model to the data, to check the adequacy of the respective model, one usually computes various residual. The Pearson residual is computed as the raw residual (y-m), scaled by the estimated standard deviation of y.

For a detailed discussion of residual statistics for generalized linear models, see McCullagh and Nelder (1989); see also the description of the Generalized Linear Models module.
