The first few rows of the regression matrix (Image by Author) Training the Cox Proportional Hazard Model. Next, let’s build and train the regular (non-stratified) Cox Proportional Hazards model on this data using the Lifelines Survival Analysis library:

It produces a table containing counts (proportions) for factors, mean (SD) for continuous variables and a univariable and multivariable CPH regression. A hazard is the term given to the rate at which events happen. Se hela listan på stats.idre.ucla.edu and should be included as a covariate in your Cox Regression model. Additional Features.

However, this procedure does not estimate a "baseline rate"; it only provides information whether this 'unknown' rate is influenced in a positive or a negative way by the independent variable (s) (or covariates).
