Regression analysis is a statistical method that uses a formula to predict the value of a variable based on the value of another variable. The formula for regression analysis is \(Y_{i}=f(X_{i},\beta )+e_{i}\), where: \(Y_{i}\): The dependent variable \(f\): The function \(X_{i}\): The independent variable \(\beta \): Unknown parameters \(e_{i}\): Error terms
