Webb5 juni 2024 · Logit function is typically used as a "trick" in order to run logistic regressions. Logistic regression is based on: y = Sigmoid ( X ) that is: you transform your regression equation using the Sigmoid function. However, it is much simpler, for the computer, tu run the very same model by reverting back the Sigmoid transformation. You get:
