Two of my independent variables ( condA and condB) are categorical, each with 2 levels, … WebD x y has simple relationship with the c-index: D x y = 2 ( c − 0.5). A D x y of 0 occurs when the model's predictions are random and when D x y = 1, the model is perfectly discriminating. In this case, the c-index is 0.693 which is slightly better than chance but a c-index of > 0.8 is good enough for predicting the outcomes of individuals.

WebBack to logistic regression. In logistic regression, the dependent variable is a logit, which is the natural log of the odds, that is, So a logit is a log of odds and odds are a function of P, the probability of a 1.

Let’s say X1 and X2 are features of a dataset and Y is the class label or output that we are trying to predict. Then, If X1 and X2 interact, this means that the effect of X1 on Y depends on the value of X2 and vice versa then where is the interaction between features of the dataset. ray\\u0027s catcher dies
