Example of How to Use Multiple Linear Regression (MLR) As an example, an analyst may want to know how the movement of the market affects the price of ExxonMobil (XOM). In this case, the linear equation will have the value of the S&P 500 index as the independent variable, or predictor...
In multiple linear regression, it is possible that some of the independent variables are actually correlated with one another, so it is important to check these before developing the regression model. If two independent variables are too highly correlated (r2 > ~0.6), then only one of them sho...
Multiple Regression - ExampleI run a company and I want to know how my employees’ job performance relates to their IQ, their motivation and the amount of social support they receive. Intuitively, I assume that higher IQ, motivation and social support are associated with better job performance....
USING FACTOR ANALYSIS AND MULTIPLE LINEAR REGRESSIONS: AN EXAMPLE IN SATISFACTION WITH LIFE IN SLOVENIAThis paper presents the research about satisfaction with life in Slovenia. There were analysed the impact of gender, age, level of education, employment status and the amount of salary on the ...
A multiple linear regression (MLR) model that describes a dependent variable y by independent variables x1, x2, ..., xp (p > 1) is expressed by the equation as follows, where the numbers α and βk (k = 1, 2, ..., p) are the parameters, and ϵ is the error term. For ...

Multiple linear regression is an extension of simple linear regression and many of the ideas we examined in simple linear regression carry over to the multiple regression setting. For example, scatterplots, correlation, and least squares method are still essential components for a multiple regre...
Multiple linear regression models are used for numerical data mining situations In. For example, demographic and historical behavior models are used to predict customer use of credit cards, based on usage and their environment To forecast the equipment failure time, often in the past through the ...
