Member Training: Exact and Randomization Tests
June 2nd, 2023 by guest contributer
Exact and randomization tests are simple from a conceptual level and need fewer assumptions than traditional parametric tests. They do require substantial computing power, but nothing that can’t be handled by the computer you have today. (more…)
Member Training: Interactions in Poisson and Logistic Regression
May 1st, 2023 by TAF Support
Interactions in statistical models are never especially easy to interpret. Throw in non-normal outcome variables and non-linear prediction functions and they become even more difficult to understand. (more…)
