In my experience, linear regression and logistic regression are two fundamental techniques in statistical modeling and machine learning. The key differences between them lie in their outcome variables and prediction objectives.
Linear regression is used when the outcome variable is continuous, and we're trying to model the relationship between a dependent variable and one or more independent variables. For example, predicting house prices based on factors like square footage, location, and the number of bedrooms.
On the other hand, logistic regression is used when the outcome variable is binary or categorical, and we're trying to model the probability of an observation belonging to a particular class. For instance, predicting whether a customer will make a purchase or not based on their browsing history and demographic information.
So, in summary, when dealing with a continuous outcome variable, I would apply linear regression, and when working with a binary or categorical outcome variable, I would use logistic regression.
