What type of regression is used for categorical data in a survival analysis?

Linear regression
Logistic regression
Cox regression
ANOVA

The correct answer is: Cox regression

In survival analysis, the outcome of interest is typically time until an event occurs, such as death or recovery. Linear regression is used for continuous outcomes and would not be appropriate for categorical data. Logistic regression is used for binary outcomes and therefore is not the best choice for survival analysis. ANOVA is typically used for comparing means of continuous variables and would not be suitable for categorical data in survival analysis. Cox regression, on the other hand, is used for modeling the relationship between predictors and time-to-event outcomes, making it the most appropriate choice for categorical data in survival analysis.
