The parameters of the linear regression line,, can be estimated using the method of Ordinary Least Squares. 2 Alternative formulas for the slope coefficient.the Pearson product moment correlation coefficient. dependent and independent) can be measured using a correlation coefficient e.g. The linear relationship between the two variables (i.e. Where is the dependent variable, is the y intercept, is the gradient or slope of the line, is independent variable and is a random term. Another way to put it is that simple linear regression is used to develop an equation by which we can predict or estimate a dependent variable given an independent variable. One example could be the relationship between muscle strength and lean body mass. Simple linear regression is used in situations to evaluate the linear relationship between two variables. Simple linear regression is a form of multiple regression. ![]() ![]() A simple linear regression is a linear regression in which there is only one covariate (predictor variable).
