Witryna9 cze 2024 · 3. I've run a binary logistic regression in R, using brms. I have one independent variable (Age) and 3 dependent variables, Y1, Y2, and Y3. These dependent variables are all pass/fail tasks. For each task, I want to model the probability of passing as a function of age. But, I also want to test the hypothesis that those who … WitrynaHypothesis test - 1. The brms package offers several ways of testing hypotheses. The hypothesis () function computes an evidence ratio (equivalent to a Bayes factor for point hypotheses, such as \ (\theta = 0\)). When testing point hypotheses, this evidence ratio is computed using the Savage-Dickey method. cara download film di netflix web
