The Goldfeld-Quandt Test can test for heteroscedasticity. The test splits the multiple linear regression data in high and low value to see if the samples are significantly different . If homoscedasticity is present in our multiple linear regression model, a non-linear correction might fix the problem, but might sneak multicollinearity into the ...

When there are more than one independent variable it is called as multiple linear regression. This statistics online linear regression calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.

A Second –Order Linear Model (Two Predictor Variables) Y= β 0 +β 1 X 1 +β 2 X 2 + β 3 X 1 X 2 + β 4 X 1 2 ++ β 5 X 2 2 +ε. Example of Multiple Linear Regression in DMAIC. Multiple Linear Regression will be used in Analyze phase of DMAIC to study more than two variables.

In the previous part of the Introduction to Linear Regression, we discussed simple linear regression. Simple linear regression is a basic model with just two variables an independent variable x, and a dependent variable y based on the equation \mathrm{y}=\mathrm{b0}+\mathrm{b} 1^{*} \mathrm{X} In real-world, the simple linear regression is ...

The general form of the multiple linear regression model is simply an extension of the simple linear regression model For example, if you have a system where X1 and X2 both contribute to Y, the multiple linear regression model becomes Yi = β 0 + β 1X1 + β 11X12 + β 2X2 + β 22X22 + β 12X1X2 + ε

Besides these, you need to understand that linear regression is based on certain underlying assumptions that must be taken care especially when working with multiple Xs. Once you are familiar with that, the advanced regression models will show you around the various special cases where a different form of regression would be more suitable.
