How To Do Least Squares Regression By Hand. Now there are two equations and two unknowns ( m and b ). Since some of the distances are positive and some are negative, the distances are squared to make them additive, and the best line is one that gives lowest sum or least squares.

This is done by finding the partial derivative of l, equating it to 0 and then finding an expression for m and c. Suppose we have the following dataset that shows the weight and height of seven individuals: When calculating least squares regressions by hand, the first step is to find the means of the dependent and independent variables.
