Standard CoxPH solvers (lifelines, scikit-survival, R survival) load the full cohort into memory before fitting, so on registry-scale data they exhaust RAM long before the computation is hard.

Game developers didn’t have it easy in the 1990s. Because they had extremely limited computing power, they had to write their code as efficiently as possible. Consider the first-person shooter Quake ...

Firth penalization reduces small-sample bias and produces finite estimates even when standard MLE fails due to (quasi-)complete separation or monotone likelihood. Standard maximum-likelihood logistic ...
