Model evaluation IQRlogisticRegression projects

Two methods of model evaluation are applied to an IQRlogisticRegression object:

  1. Hosmer-Lemeshow goodness of fit test.

  2. Area under the receiver operating characteristic (ROC) curve. In order to consider that the logistic regression model developed has sufficient predictive performance, one could usually accept models with an AUC ROC>0.75 and a p value>0.05 for the Hosmer-Lemeshow test. Of course, personally preferred different values would be possible to define.

  filename = NULL,
  SIGNIF = 3,
  AUCthreshold = 0.75,
  HLpValueThreshold = 0.05



Path to the IQRlogisticRegression to conduct the model evaluation for.


File name (with path) to store the resulting figure.


Number of significant digits used for the displayed p-value.


Threshold for acceptance of model (calculated value should lie >=)


Threshold for acceptance of model (calculated value should lie >=)


IQRoutputFigure object with all results.
