![]() The response variable is binary – it can only take on two values.Įxample: Medical researchers may fit a logistic regression model using exercise and smoking habits to predict the likelihood that an individual experiences a heart attack.Logistic regression is used to fit a regression model that describes the relationship between one or more predictor variables and a binary response variable. Resource: An Introduction to Multiple Linear Regression 2. Since the relationship between these two variables is likely linear (more money spent on advertising generally leads to an increase in sales) and the response variable (total sales) is a continuous numeric variable, it makes sense to fit a linear regression model. The response variable is a continuous numeric variable.Įxample: A retail company may fit a linear regression model using advertising spend to predict total sales.The relationship between the predictor variable(s) and the response variable is reasonably linear.Linear regression is used to fit a regression model that describes the relationship between one or more predictor variables and a numeric response variable. In this article we share the 7 most commonly used regression models in real life along with when to use each type of regression. The basic goal of regression analysis is to fit a model that best describes the relationship between one or more predictor variables and a response variable. ![]() Regression analysis is one of the most commonly used techniques in statistics. ![]()
