Predictors
Figure 12-3
Cox Regression dialog box, Predictors tab
The Predictors tab allows you to specify the factors and covariates used to build model effects.
Factors
.
Factors are categorical predictors; they can be numeric or string.
Covariates. Covariates are scale predictors; they must be numeric.
Time-Dependent Predictors. There are certain situations in which the proportional hazards
assump
tion does not hold. That is, hazard ratios change across time; the values of one (or more)
of your predictors are different at different time points. In such cases, you need to specify
time-dependent predictors. For more information, see the topic Dene Time-Dependent Predictor
on p. 79. T
ime-dependent predictors can be selected as factors or covariates.
