This is my first program. It plots x and y data and fits a linear, exponential, or quadratic regression line to them. It then plots the residuals.
Be sure to enter the data using "{}" or by entering a pre made list "L1". 
Enter the data and choose a regression model. The program will plot x and y with the regression line. R values are displayed in the upper right hand corner. Press enter to look at the residuals plotted.
