Version 8.2 of the #rstats rms package is now on CRAN. This is a milestone release due to major improvements and extensions of the general-purpose semiparametric modeling function orm, including improved computational accuracy and two types of random effects.

I've updated simulations of performance of various methods for estimating S(t|x) vs. continuous x with right censoring. The new loess method is a winner. fharrell.com/post/kmove #Statistics

There is no straightforward nonparametric smoother for estimating a smooth relationship between a continuous variable and the probability of survival past a fixed time when censoring is present....

I've been going back and forth between @zeddotdev and @CotEditor and have found that I prefer Cot when not using AI. For the one language I needed syntax highlighting for (@typstapp ) that was not built-in to Cot, Claude quickly wrote the Cot plug-in needed.

I have a new favorite editor/IDE: Zed. Open-source, blazing fast, built-in AI operability, easy to use. Heard that lots of developers are dropping Visual Studio Code for Zed. Has R and Quarto extensions. zed.dev

Any new field that comes on the scene quickly can vanish just as quickly. Witness data science, personalized medicine, precision medicine, many 'omics, and hopefully digital twins.

Data science feels so dead now that it's like it never existed at all. AI seems to have killed it
