There are many types of Regression analysis, like Linear Regression, Logistic Regression, Multiple Regression, Ridge Regression, Lasso, and many more. In this article we will discuss Multiple Regression in detail. Multiple Regression Multiple Regression is a special kind of regression model that is ...
Regression analysis is used in graph analysis to help make informed predictions on a bunch of data. With examples, explore the definition of...
Multivariate Regression Analysis: A Practical Introduction with Examples in SPSS and StataThis final chapter provides an introduction into multivariate regression modeling.

Stat 112 D. Small Example of Regression Analysis: Emergency Calls to the New York Auto Club The AAA Club of New York provides many services to its members, including travel planning, traffic safety classes and discounts on insurance. The service with the highest profile is its Emergency Road ...
Example of multicollinearityHere's an example of how this concept works:A financial analyst is performing multiple regression analysis for a large data set that represents a sample of client income averages. The analyst establishes the indicator variables for the data to recover from business ...
There are many ways to conduct a multivariate analysis. Below we’ll explore some of the most common methods. Multiple linear regression Multiple linear regression is an example of a dependent technique that looks at the relationship between one dependent variable and two or more independent variable...
Depending on the nature and behavior of a data set, different types of regression analysis may be appropriate. For example, if the data has a roughly linear relationship then a linear regression would be best, whereas logistic regression would be ideal a...
Assumptions of multiple linear regression Multiple linear regression makes all of the same assumptions assimple linear regression: Homogeneity of variance (homoscedasticity): the size of the error in our prediction doesn’t change significantly across the values of the independent variable. ...
When forecasting financial statements for a company, it may be useful to do a multiple regression analysis to determine how changes in certain assumptions or drivers of the business will impact revenue or expenses in the future. For example, there may be a very high correlation between the ...
A limitation is that a correlation matrix can only detect Pairwise Relationships. Therefore, it may miss more complex multicollinearity involving multiple variables simultaneously. 2. Variance Inflation Factors (VIFs) TheVariance Inflation Factor (VIF)measures how much the variance of a regression coeffi...
