How would you go from accuracy to relative error? What equations would be involved to make the process successful?

Solution

In relative error we can get accuracy through formula of calculated value-actual value as e^i =f (x^i)-y^ i , for errors calculation of error we use sum of least square errors. Here for sum to be minimum we use partial differentiation and normal equations are solved by general methods. The equations for error ( sum y)=na+b sigma x, sigma xy=a sigmax+sigma x^2
