Webb10 jan. 2024 · Simple linear regression is an approach for predicting a response using a single feature. It is assumed that the two variables are linearly related. Hence, we try to find a linear function that predicts the response value (y) as accurately as possible as a function of the feature or independent variable (x).

WebbA simple linear regression model is a mathematical equation that allows us to predict a response for a given predictor value. Our model will take the form of ŷ = b 0 + b 1 x where b 0 is the y-intercept, b 1 is the slope, x is the predictor variable, and ŷ an estimate of the mean value of the response variable for any value of the predictor variable.
