Logistic regression step failed
Witryna16 lip 2024 · In unpenalized logistic regression, a linearly separable dataset won't have a best fit: the coefficients will blow up to infinity (to push the probabilities to 0 and 1). When you add regularization, it prevents those gigantic coefficients. WitrynaA frequent problem in estimating logistic regression models is a failure of the likelihood maximization algorithm to converge. In most cases, this failure is a consequence of …
