TL;DR: In this paper, the authors used dummy variables 1 and 0 as an alternative to analyze the variance and covariance to compare the relationship among groups of observations and showed that the dummy variable regression not only can perform a good result as performed by the standard technique, but simultaneously test the difference between two regression lines whether due to slope coefficients or intercept terms.

TL;DR: In this paper, the performance of optimum ridge regression analysis (OPT) was compared with the ordinary least-squares method (OLS) for water storage computation for Lake Okeechobee, Florida was used as an example to demonstrate the techniques of applications.
