For a given data set of value pairs (xi, yi), where xi is an independent variable, find the function yi = f(xi) + εi such that the sum of squares of errors ei is minimal. To do that, first select the type of the function that you think corresponds the data set (xi, yi), and then enter in the table the values of the data set.
Please select the type of a function yi = f(xi) + εi you wish to fit:
