NettetNormally distributed errors: Classical Linear models assume the errors of regression, also known as the residuals, are normally distributed with mean zero.This condition is also difficult to meet in real life. Non-correlated variables: Finally, the regression variables are assumed to be non-correlated with each other, and preferably independent of each other.

Numerous extensions of linear regression have been developed, which allow some or all of the assumptions underlying the basic model to be relaxed. The very simplest case of a single scalar predictor variable x and a single scalar response variable y is known as simple linear regression. The extension to multiple and/or vector-valued predictor variables (denoted with a capital X) is k… NettetWhat is a linear model? If we graph data and notice a trend that is approximately linear, we can model the data with a line of best fit. A line of best fit can be estimated by drawing a line so that the number of points above and below the line is about equal.
