         Regression Analysis:

             Regression analysis helps to estimate the changes when dependent variable change when one or more independent variable changes due to some factor. The formula to calculate the regression analysis is Y=a+bX+E. Here Y is the independent variable and X is the dependent Variable and E is the error term.

         Non-linear equations contains more equations, at least one non-linear equation will be there in the overall equations. In that case, we need to solve the linear equation first and then the results of the linear equations should be substitute with the non-linear equation to get a new result. This process is know as non-linear equation.
