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

Linear regression assumes a linear relationship, is sensitive to outliers, and may not perform well if the assumptions (like homoscedasticity or normality) are violated.

Learn how to graph linear regression in Excel. Use these steps to analyze the linear relationship between an independent and a dependent variable.

Then conditions on the set F and on the xkm are obtained such that the least squares estimators (LSE) of the parameters β1, ⋯, βq are consistent in Case (a) (Theorem 1) or asymptotically normal in ...

Nonlinear regression is a form of regression analysis in which data fit to a model is expressed as a mathematical function.

We consider the semiparametric linear regression model with censored data and with unknown error distribution. We describe estimation equations of the Buckley-James type that admit $\sqrt ...
