Regression is used to fit a line or curve through a set of data points using a least squares fit.
The type of regression for data analysis is chosen from a separate list located below the data window. Types of regression analysis are Linear, Exponential, Logarithmic, Power, Hyperbolic, and two Rational functions. The equation used for the regression is listed along with the name. The statistical information is automatically updated in the data display area. There are two boxes for entering a test X or Y data point.
