Contains the time to event or time to censoring. With interval censoring, specify two Y variables, where one Y variable gives the lower limit and the other Y variable gives the upper limit for each unit.
Specify location and scale effects using these options. For more information about the Construct Model Effects options, see Construct Model Effects in the Fitting Linear Models book.
Choose the desired response distribution that is appropriate for your data. Choose the All Distributions option to fit all the distributions and compare the fits. If you choose All Distributions, the report shows a comparison of the distribution fits. See The Parametric Survival - All Distributions Report.
Note: By default, the All Distributions option fits a model for the log-location-scale distributions that appear above All Distributions in the Distribution menu. Select Preferences > Platforms > Fit Parametric Survival > Include location-scale distributions in All Distributions to change the behavior of the All Distributions option to also include the location-scale distributions.
