This study aims to create a computer program designed to apply the principle of curve fitting using the method of least squares. The general problem in curve fitting is to find an analytic expression of the form y = f(x) for the functional relationship suggested by the given data.This module is designed to accept data given by the user and plot these data with the corresponding X and Y coordinates. With the curve chosen by the user, it will consequently estimate the parameters of the curve, which makes the sum of squares of error minimum by means of least squares estimation. Using the estimated parameters, the curve is graphed by the computer. Then, the computation for the residuals of data is shown. Lastly, the graph of X against the residuals is plotted.
