Fit Proportional Hazards Platform Options

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

Likelihood Ratio Tests

Shows or hides likelihood ratio tests for each effect. Each test compares the log-likelihood for the fitted model to the log-likelihood for the model that removes an effect.

Wald Tests

Shows or hides 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 that are shown in the Parameter Estimates table. When this option is selected, a profile likelihood confidence interval appears. Otherwise, a Wald interval appears. 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.

Hazard Ratios

Shows or hides the hazard ratios for the effects. For continuous columns, unit hazard ratios and range hazard ratios are calculated. The Unit Hazard Ratio is Exp(estimate) and the Range Hazard Ratio is Exp[estimate*(xMaxxMin)]. The Unit Hazard Ratio shows the risk change over one unit of the regressor, and the Range Hazard Ratio shows the change over the whole range of the regressor. For categorical columns, hazard 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 Hazard Ratio report, right-click in the report and select Columns > Reciprocal.

Model Dialog

Shows the completed Fit Model launch window for the current analysis.

Effect Summary

Shows or hides the Effect Summary report, which enables you to interactively update the effects in the model. See “Effect Summary Report” in Fitting Linear Models.

See “Local Data Filters in JMP Reports”, “Redo Menus in JMP Reports”, “Group Platform”, and “Save Script Menus in JMP 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.

Redo

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.

Platform Preferences

Contains options that enable you to view the current platform preferences or update the platform preferences to match the settings in the current JMP report.

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.

Note: Additional options for this platform are available through scripting. Open the Scripting Index under the Help menu. In the Scripting Index, you can also find examples for scripting the options that are described in this section.
