WebbFor binary classification, a probability less than .5 will predict 0 while a probability greater than 0 will predict 1. After the model has been computed, it’s best practice to evaluate the how well the model predicts the dependent variable, which is called goodness of fit. The Hosmer–Lemeshow test is a popular method to assess model fit. airbnb con piscina privada
