The least squares regression analysis is mostly used to estimate the best fit for a given set of data by minimizing the variation in the values of the offsets. For example, in an experimental data where there are independent and dependent variable, the least square regression analysis can be used to determine the effects of the change in the dependent variable on the independent variable.
