Nettet5. jan. 2024 · Linear regression is a simple and common type of predictive analysis. Linear regression attempts to model the relationship between two (or more) variables by fitting a straight line to the data. Put simply, linear regression attempts to predict the value of one variable, based on the value of another (or multiple other variables). http://cs231n.stanford.edu/slides/2024/cs231n_2024_ds02.pdf
