Cell Count and Residuals

Cell count and residuals

The Pearson goodness-of-fit statistic is based on the cells of the cell count and residuals table, the top half of which is shown here. Cells in the table represent the cross-classifications of the factors and dependent variable specified on the main dialog box. Thus, even though Gender is not used in the model, it is used in the test of model fit. Thus, the first row of the table pertains to inactive males under the age of 31 who preferred the breakfast bar.

  • The observed columns report the number and percentage of cases observed in the data file that are in the covariate pattern.
  • The expected columns report the number and percentage of cases you would expect to see in the covariate pattern if the model is correct.
  • Residuals are measures of the difference between the observed and predicted values. Large residuals can indicate covariate patterns that are not well fit by the model.
