Regression Analysis

1. Regression analysis is a method for determining the relationship between two or more variables. Simple regression analysis involves one dependent variable and one independent variable. Multiple regression analysis involves more than one independent variable. Often, the determination of whether there is a relationship, and the strength of that relationship if there is one, is called correlation analysis. Regression analysis is purely the determination of the actual regression equation (the intercept and slope coefficients of the regression line). See also coefficient of correlation and coefficient of determination and standard error of the estimate and high-low method. A statistical analysis tool that quantifies the relationship between a dependent variable and one or more independent variables.
