WebOct 28, 2024 · Logistic regression is a method we can use to fit a regression model when the response variable is binary. Logistic regression uses a method known as maximum likelihood estimation to find an equation of the following form: log [p (X) / (1-p (X))] = β0 + β1X1 + β2X2 + … + βpXp. where: Xj: The jth predictor variable.

WebDec 20, 2016 · 1 Answer Sorted by: 3 The Wald test is used to test if a predictor is significant or not, of the form: W = (beta_hat - beta_0) / SE (beta_hat) ~ N (0,1) So somehow you'll want to input the predictors into the test. Judging from the example of the t.test and f.test, it may be simpler to input a string or tuple to indicate what you are testing. WebNow, when you expect that this perfect separation is not just a byproduct of your sample, but could be true in the population, you specifically don't want to handle this: use this separating variable simply as the sole predictor for your outcome, not employing a model of any kind.
