Pattern Values

The pattern values table lists the values that define each predictor pattern. In addition to the predictors in the model, the start and end times for the survival interval are displayed. For analyses run from the dialogs, the start and end times will always be 0 and unbounded, respectively; through syntax you can specify piecewise constant predictor paths. See the topic PATTERN Subcommand for more information.

The reference pattern is set at the reference category for each factor and the mean value of each covariate (there are no covariates in this model). For this dataset, the combination of factors shown for the reference model cannot occur, so we will ignore the log-minus-log plot for the reference pattern.
Patterns 1.1 through 1.4 differ only on the value of History of myocardial infarction. A separate pattern (and separate line in the requested plot) is created for each value of History of myocardial infarction while the other variables are held constant.
