pancho villa tattoo designs What is the Least Squares Regression method and why use it? Least squares is a method to apply linear regression. It helps us predict results based on an existing set of data as well as clear anomalies in our data. Anomalies are values that are too good, or bad, to be true or that represent rare cases.Fitting the Multiple Linear Regression Model.
