Analyzing Residuals

You can view residual plots in ADX by selecting Model arrow Check Assumptions and clicking the Perform Residual Analysis button. The interactive display features are the same as those of the scatter plot, and you can display the following diagnostics by clicking the BY Axis button:

  • Residuals
  • Standardized residuals
  • Normal score for residuals
  • Cook's d influence statistic
  • PRESS statistic (deleted residuals)
  • Studentized deleted residuals
