Finally, we would like to make you aware that a viable alternative (or complement) to Cox regression is Laplace regression. Laplace regression can be used to estimate the effect of exposures (or treatments) on survival percentiles and thereby it allows for direct interpretation of the exposure–outcome association in terms of time gained or lost.
We will not go through Laplace regression in this version of the guide, but if you are interested, we suggest that you install the laplace regression package and then review the help file.
