WebResiduals are certainly less informative for logistic regression than they are for linear regression: not only do yes/no outcomes inherently contain less information than … WebIn this case, the denominator of the Pearson residual will tend to understate the true variance of the \(Y_i\), making the residuals larger. If the plot looks like a horizontal band but \(X^2\) and \(G^2\) indicate lack of fit, an adjustment for overdispersion might be warranted. A warning about this, however: If the residuals tend to be too ...
