NettetThe Pearson correlation coefficient [1] measures the linear relationship between two datasets. Like other correlation coefficients, this one varies between -1 and +1 with 0 implying no correlation. Correlations of -1 or +1 imply an exact linear relationship. Positive correlations imply that as x increases, so does y. Nettet27. des. 2024 · Logistic Model. Consider a model with features x1, x2, x3 … xn. Let the binary output be denoted by Y, that can take the values 0 or 1. Let p be the probability of Y = 1, we can denote it as p = P (Y=1). Here the term p/ (1−p) is known as the odds and denotes the likelihood of the event taking place.
