coh_eff_hr {vaccineff} | R Documentation |
The function relies on the implementation of the Cox model for
proportional hazards from the package {survival}
The proportional hazards
hypothesis is tested using the Schoenfeld test, and the resultant p-value is
provided in the results. Log-log plots are also calculated using the
Kaplan-Meier survival estimator to provide a visual test for the proportional
hazards hypothesis. The function returns a list with the method called, the
estimation of VE (CI95%), the p-value of the Schoenfeld test, and the log-log
plot.
