    Lower values of these statistics indicate a better fitted model. The Pearson dispersion statistic is used with Poisson, negative binomial, and binomial models as an indicator of excessive correlation in the data. Likelihood based models, being derived from a PDF, assume that observations are independent. When they are not, correlation is observed in the data. Values of the Pearson dispersion greater than 1. Some statisticians have used the deviance statistic on which to base the dispersion, but simulation studies have demonstrated that Pearson is the correct statistic. See Modeling count data in this Encyclopedia for additional information. From the outset, generalized linear models software has offered users a number of useful residuals which can be used to assess the internal structure of the modeled data. Both are observation-based statistics, providing the proportionate contribution of an observation to the overall Pearson Chi2 and deviance fit statistics. However, they are seldom calculated in such a manner. Both the Pearson and deviance residuals are usually employed in standardized form. Standardized Pearson residuals are normalized to a standard deviation of 1. Another residual now finding widespread use is the Anscombe residual. First implemented into GLM software in , it now enjoys use in many major software applications.

    Another residual now finding widespread use is the Anscombe residual. First implemented into GLM software in , it now enjoys use in many major software applications. The Anscombe residuals are defined specifically for each family, with the intent of normalizing the residuals as much as possible.

    A standard use of this statistic is to graph it on either the fitted value, or the linear predictor. Values of the Anscombe residual are close to those of the standardized deviance residuals. Information was collected on the survival status, gender, age, and ticket class of the various passengers.

    Note the fact that 1st class passengers had a near 6 times greater odds of survival than did 3rd class passengers. The statistics displayed in the model output are fairly typical of that displayed in GLM software applications.
