Measuring goodness of fit in logistic regression Using R


This is a good summary on the measure of the goodness of fit in logistic regression. The data can be searched online. It was based on the icu data available from the Hosmer-Lemeshow logistic regression book

The analysis in R.

The discussion is on:

  1. Chi-square goodness of fit tests and deviance
  2. Hosmer-Lemeshow tests
  3. Classification tables
  4. ROC curves
  5. Logistic regression R2
  6. Model validation via an outside data set or by splitting a data set
