Thank you for the detailed issue! :100:
You are welcome.
(I may also add that we are RStudio Enterprise customers with an air-gapped environment; so having {censored} on CRAN and thus RSPM is something we are eagerly awaiting to be able to use the package in our R&D projects. But quality comes first, of course :wink:).
Feature
Hi there, this is a hugely welcome addition to the R stack for the pharma community! Thanks so much for working on this.
Apart from the issues which are still on your ToDo list, I would like to highlight a particular model which has been shown to work very well in benchmarks as well as in practice, Multi-task Logistic Regression (MTLR).
The approach is originally from NIPS 2011 and already available on CRAN by @haiderstats; it's prediction modes are displayed in the Vignette. The package is actively maintained on Github. There is a very detailed Rmd by the package author that compares different R models for estimating per-patient survival probabilities.
The following resources contain the original paper and subsequent benchmarks and applications; MTLR does very well in the benchmarks:
The methods's main advantages are that it provides per-patient survival probabilities (i.e., it predicts the survival function itself) across a range of times (i.e., it allows for feature effects to vary through time). Also, it works with many different forms of censoring events, which makes it very versatile (although it still does not allow for missing values, unfortunately).
To quote from the R package vignette:
