Save Only saves the created code to the Program Editor, but does not run the code. Cancel closes the dialog box without saving or executing a command. Clear empties the fields so information can be re-entered. Help opens the Help topic associated with the module being used. (Currently Disabled). Try It From the Analysis Command Tree, use the READ command to open a PRJ project file. Select a form or table. From the Analysis Command Tree, click Advanced Statistics > Cox Proportional Hazards. The Cox Proportional Hazards dialog box opens. From the Censored Variable drop-down list, select the variable that indicates whether the case is a failure or a censored case. From the Value for Uncensored drop-down list, select the value of the censored variable that indicates a failure. From the Time Variable drop-down list, select the variable that indicates at which time the failure or censorship occurred. From the Time Unit drop-down list, select the unit in which the time variable is expressed, if needed. From the Test Group Variable drop-down list, select the discrete variable used to divide cases into groups. In the Cox model, there is no essential difference between the group variable and other predictor terms. For this reason, using the group variable is optional. From the Other Variables drop-down list, select the predictor variables. If you select any predictor variables, Make Dummy will be activated. Selecting will allow a numeric variable to become discrete rather than continuous; the variable is enclosed in parentheses to indicate that dummy variables are created. If a predictor variable enclosed in parentheses is selected in the list, the Make Dummy button changes to Make Continuous. Selecting it makes the variable continuous. If you select more than one, the Make Dummy button changes to Make Interaction. Selecting it results in all possible combinations of the selected variables being added to the regression as interaction terms. Click Graph Options. The Cox Graph Options dialog box opens. From the Plot Variables drop-down list, select a graph type. From the list box, select a variable(s) to graph.
