Regression

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.

I'm hunting for this calculator for 2 month! This is the best calculator on android. Um... just some more thing? They are Sigma and ^-1 and AUTO PARENTHESIS OPENING FUNCTION(like Ti-Nspire). Just set always starting with invisible opening parenthesis on new line(including in fraction line). If you add these function, this calculator will be MASTERPIECE. I'm sure. Thank you!
