In statistics, linear regression is a technique for estimating the relationship between an independent variable, X, and its scalar result, the dependent variable, Y, derived from a series of X-Y relationships. The computational routine involves trying to fit a straight line between a scatter plot of X-Y coordinates such that the sum of the squared differences between each dependent outcome, Yi, and the line computed at each Xi is minimized. Also, changing the form of the regression equation from Y = function(X) to X = function(Y) is allowed along with estimation of the dependent variable amount from a user-specified independent variable amount.

GraphNCalc83 is a modern version of the classic graphing calculator. The familiar calculator keyboard, arrow keys and functions are enhanced with full touch input for all graphs, editors and menus. Pop up bubble help displays function arguments during problem entry and program editing.
I would recommend buying the Scientific Graphing Calculator 2 instead of this app. That said, I will be maintaining this app. Thanks
Simple Stat is an application that can perform statistics tests which are commonly used in first year university statistics course. Simple Stat is very easy to use, and suits first year statistics students very well. The statistics tests that are included in Simple Stat are:- Z-test for mean- Z-test for proportion- T-test- Two sample t-test- Paired t-test
