The project is using supervised machine learning via a binary logistic regression model to assess probability of death and poor functional outcome in a group of patients. I have trained a new set of regression models … WebLogistic regression with built-in cross validation. Notes The underlying C implementation uses a random number generator to select features when fitting the model. It is thus not uncommon, to have slightly different results for the same input data. If that happens, try with a smaller tol parameter.
