Discover how linear regression works, from simple to multiple linear regression, with step-by-step examples, graphs and real-world applications.

Regression analysis comes in different forms: simple, multiple, linear and nonlinear. In s imple regression analysis, there is only one independent variable, whereas multiple regression analysis ...

We propose two empirical methods of canonical analysis based on polynomial regression to do away with the assumption of linearity in modeling the relationships between the variables in X and Y. They ...

An algorithm is presented for nonlinear least squares estimation in which the parameters to be estimated can be regarded as all nonlinear (the traditional approach) or reclassified as linear-nonlinear ...
