WebThe result is called the Pearson residual because the square of \( p_i \) is the contribution of the \( i \)-th observation to Pearson’s chi-squared statistic, which was introduced in Section 3.2.2, Equation 3.14. With grouped data the Pearson residuals are approximately normally distributed, but this is not the case with individual data. WebThe interpretation of the plot is the same whether you use deviance residuals or Pearson residuals. When the model uses the logit link function, the distribution of the deviance residuals is closer to the distribution of residuals from a least squares regression model.
