http://www.pythonfordatascience.org/logistic-regression-python/ WebbThis is not the case in linear regression. - R^2 value is always higher for a given set of data in a logistic regression model than in a linear one and RMSE value is lower. This shows that Logistic regression model can predict data more accurately. - Th value predicted using linear model is continuous and can range outside 0 and 1. timothy leahy aptimWebbIn logistic regression, the coeffiecients are a measure of the log of the odds. Given this, the interpretation of a categorical independent variable with two groups would be "those who are in group-A have an increase/decrease ##.## in the log odds of the outcome compared to group-B" - that's not intuitive at all. parry note

WebbVery nice post, thank you! I was toying around with it and have a fun suggestion for your regression with the quadratic term of X1: I know it doesn’t make a difference in terms of the plots and this is all about plots, but I think you could improve your quadratic model by using poly(X1, 2) instead of directly including X1+I(X1^2) to obtain orthogonal terms for … Webba logistic regression model, and the K nearest algorithm.

WebbLogistic regression finds the best possible fit between the predictor and target variables to predict the probability of the target variable belonging to a labeled class/category. Linear regression tries to find the best straight line that predicts the outcome from the features.
