Can linear regression be curved
WebLinear regression is a process of drawing a line through data in a scatter plot. The line summarizes the data, which is useful when making predictions. WebIn statistics, a regression equation (or function) is linear when it is linear in the parameters. While the equation must be linear in the parameters, you can transform the predictor variables in ways that produce curvature. For instance, you can include a squared variable to produce a U-shaped curve. Y = b o + b 1 X 1 + b 2 X 12.
