Logisticregression takes no arguments
Witryna6 kwi 2024 · Logistic regression uses logit function, also referred to as log-odds; it is the logarithm of odds. The odds ratio is the ratio of odds of an event A in the presence of the event B and the odds of event A in the absence of event B. logit or logistic function P is the probability that event Y occurs. P(Y=1) P/(1-P) is the odds ratio
