Output functions
The package has function that automatically prints the crude unadjusted estimates
of a function next to the adjusted estimates, a common practice for medical
publications. The forestplot wrappers allows for easily displaying regression
estimates, often convenient for models with a large number of variables.
There is also functionality that can help you comparing different models,
e.g. subsets of patients or compare different regression types.Time-splitter
When working with Cox regressions the proportional hazards can sometimes be violated.
As the tt() approach doesn't lend itself that well to big datasets I often
rely on time-splitting the dataset and then using the start time as an interaction
term. See the function timeSplitter and the associated vignette("timeSplitter").Other regression functions
In addition to these funciton the package has some extentions to linear regression
where it extends the functionality by allowing for robust covariance matrices.
by integrating the sandwich-package for rms::ols().Important notice
This package has an extensive test-set for ensuring that everything behaves as expected.
Despite this I strongly urge you to check that the values make sense. I commonly use
the regression methods available in the rms-package and in the stats package.
In addition I use the coxph in many of my analyses and should
also be safe. Please send me a notice if you are using the package with some other
regression models, especially if you have some tests verifying the functionality.
