WebOct 18, 2024 · Linear regression is basically line fitting. It asks the question — “What is the equation of the line that best fits my data?” Nice and simple. The equation of a line is: Y = b0 + b1*X. Y, the target variable, is the thing we are trying to model. We want to understand (a.k.a. explain) its variance. In statistics, variance is a measure of ... WebThe simple linear regression model for nobser-vations can be written as yi= β 0 +β 1xi+ei, i= 1,2,··· ,n. (1) The designation simple indicates that there is only one predictor variable x, and linear means that the model is linear in β 0 and β 1. The intercept β 0 and the slope β 1 are unknown constants, and
