Simple Linear Regression Like correlation, regression also allows you to investigate the relationship between variables. But while correlation is just used to describe this relationship, regression allows you to take things one step further; from description to prediction. Regression allows you to model the relationship between variables, which enables you to make predictions about what one

The Simple Linear Regression Model: estimate, based on the sample, for the True Regression Line. OK SO WHAT! Well the true connection between any y and x is described by the probabilistic model: yx=+ +?01? ? and so even if we knew x and the coefficients ?0 and ?1 we couldn’t determine y because of the random factor ?. Instead we use our sample data to find estimates for the

Thus, for example, if the correlation is r XY = 0.5, then r XY 2 = 0.25, so the simple regression model explains 25% of the variance in Y in the sense that the sample variance of the errors of the simple regression model is 25% less than the sample variance of Y.
