Witryna11 lip 2024 · The logistic regression equation is quite similar to the linear regression model. Consider we have a model with one predictor “x” and one Bernoulli response variable “ŷ” and p is the probability of ŷ=1. The linear equation can be written as: p = b 0 +b 1 x --------> eq 1. The right-hand side of the equation (b 0 +b 1 x) is a linear ... WitrynaThe project involves using logistic regression in Python to predict whether a sonar signal reflects from a rock or a mine.
