Cox Node Stepping Criteria

Removal criterion. Select Likelihood Ratio for a more robust model. To shorten the time required to build the model, you can try selecting Wald. There is the additional option Conditional, which provides removal testing based on the probability of the likelihood-ratio statistic based on conditional parameter estimates.

Significance thresholds for criteria. This option allows you to specify selection criteria based on the statistical probability (the p value) associated with each field. Fields will be added to the model only if the associated p value is smaller than the Entry value and will be removed only if the p value is larger than the Removal value. The Entry value must be smaller than the Removal value.
