Figure 15.4 The Fit Proportional Hazards Launch Window 

Tip: To change the alpha level, click the Model Specification red triangle and select Set Alpha Level.

For more information about the options in the Select Columns red triangle menu, see Column Filter Menu in Using JMP.

The Fit Proportional Hazards launch window contains the following options:

Time to Event

Contains the time to event or time to censoring.


Nonzero values in the censor column indicate censored observations. (The coding of censored values is usually equal to 1.) Uncensored values must be coded as 0.


Column whose values are the frequencies or counts of observations for each row when there are multiple units recorded.


Performs a separate analysis for each level of a classification or grouping variable.

Construct Model Effects

Enters effects into your model. For more information about the Construct Model Effects options, see Construct Model Effects in Fitting Linear Models.


Indicates the fitting method. Proportional Hazard should always be selected.

Censor Code

Identifies the value in the Censor column that designates right-censored observations. After a Censor column is selected, JMP attempts to automatically detect the censor code and display it in the box. To change this, you can click the red triangle and select from a list of values. You can also enter a different value in the box. If the Censor column contains a Value Labels column property, the value labels appear in the list of values. Missing values are excluded from the analysis.
