I have been working on adding Regression to the calculator.  In this graph mode, points are entered and then a best fit line is calculated.

Above I have entered some points for linear regression.  The equation is then calculated and displayed at the top.  The equation can be changed between linear, logarithmic, exponential, power, quadratic polynomial or cubic polynomial.  When graphed, the points entered and equation will be drawn.
