Fit Proportional Hazards Options

The Proportional Hazards Fit red triangle menu contains the following options:

Likelihood Ratio Tests

Produces tests that compare the log-likelihood from the fitted model to one that removes each term from the model individually.

Wald Tests

Produces chi-square test statistics and p-values for Wald tests of whether each parameter is zero.

Likelihood Confidence Intervals

Specifies the type of confidence intervals shown in the Parameter Estimates table for each parameter. When this option is selected, a profile likelihood confidence interval appears. Otherwise, a Wald interval is shown. In the report, the interval type is noted below the Parameter Estimates table. This option is on by default when the computational time for the profile likelihood confidence intervals is not large.

Note: You can change the α level for the confidence intervals by selecting Set Alpha Level from the red triangle menu in the Fit Model launch window. The default α level is 0.05.

Risk Ratios

Shows the risk ratios for the effects. For continuous columns, unit risk ratios and range risk ratios are calculated. The Unit Risk Ratio is Exp(estimate) and the Range Risk Ratio is Exp[estimate*(xMaxxMin)]. The Unit Risk Ratio shows the risk change over one unit of the regressor, and the Range Risk Ratio shows the change over the whole range of the regressor. For categorical columns, risk ratios are shown in separate reports for each effect. Note that for a categorical variable with k levels, only k -1 design variables, or levels, are used.

Tip: To see Reciprocal values in the Risk Ratio report, right-click in the report and select Columns > Reciprocal.

Model Dialog

Shows the completed launch window for the current analysis.

Effect Summary

Shows the interactive Effect Summary report that enables you to add or remove effects from the model. See Effect Summary Report in Fitting Linear Models.

See Local Data Filters in Reports, Redo Menus in Reports, and Save Script Menus in Reports in Using JMP for more information about the following options:

Local Data Filter

Shows or hides the local data filter that enables you to filter the data used in a specific report.


Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.

Save Script

Contains options that enable you to save a script that reproduces the report to several destinations.

Save By-Group Script

Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.
