# Cox Regression Options

You can control various aspects of your analysis and output.

**Model Statistics.** You can obtain statistics for your model
parameters, including confidence intervals for exp(*B*) and correlation
of estimates. You can request these statistics either at each step
or at the last step only.

**Probability for Stepwise.** If you have selected a stepwise
method, you can specify the probability for either entry or removal
from the model. A variable is entered if the significance level of
its *F*-to-enter is less than the Entry value, and a variable
is removed if the significance level is greater than the Removal value.
The Entry value must be less than the Removal value.

**Maximum Iterations.** Allows you to specify the maximum iterations
for the model, which controls how long the procedure will search for
a solution.

**Display baseline function.** Allows you to display the baseline
hazard function and cumulative survival at the mean of the covariates.
This display is not available if you have specified time-dependent
covariates.
