Fractional logistic regression

WebOct 17, 2024 · Introduction. In simple logistic regression, we try to fit the probability of the response variable’s success against the predictor variable. This predictor variable can be either categorical or continuous. We need to quantify how good the model is. There are several goodness-of-fit measurements that indicate the goodness-of-fit. WebAn explanation of logistic regression can begin with an explanation of the standard logistic function. The logistic function is a sigmoid function, which takes any real input , and outputs a value between zero and one. [2] For …
