Pseudovalues

Webables that are called pseudovalues. Briefly, the jack- knife method is as follows: Given a set of m replicate experiments, the jth replicate is deleted and the largest eigenvalue is calculated with the remaining data. This process yields a set of m pseudovalues, the mean of which is the jackknifed estimate of the largest eigen- value. WebJul 1, 2024 · Idea / motivation I’ve set myself the challenge of reproducing the results in Table I of “Causal inference in survival analysis using pseudo-observations” by Per K. Andersen, Elisavet Syriopouloua, and Erik T. Parner. I’m doing this because I’ve seen a lot about pseudo-observations recently, and while I kind of get the gist of it, I would like to …
