Multi-Regression Analysis is a kind of Regression Analysis . It uses more than one X values.
Multi-Regression Analysis is the basic of Multi-Variable Analysis and Data Mining.
In multi regression analysis, the formula is
We can judge the goodness of fitting with coefficient of determination.
In multi regression analysis, we can see the effect of each Xi by Ai. But before this analysis, we need Normalization.
By the way, in single regression analysis,
when we take Normalization,
Ai = correlation coefficient.
So the analysis of Ai is equal to the analysis of correlation coefficient.
When X is category data Category Data, regression analysis is Broadly defined Quantification theory 1.
Actual data has network structure. In such network, X is Y of other X. To evaluate network structure, there is Path Analysis . Path Analysis is not only an application of multi Regression Analysis.
