LinFit.CorrCoef()

Type: INSTANCE FUNCTION

Purpose: Return a goodness-of-fit parameter.

The number returned is the correlation coefficient. The sign of the correlation coefficient is the same as the slope. A correlation coefficient of 1 indicates that all the variation in the y-parameter is explained by a perfect linear relationship with x. A correlation coefficient of zero indicates there is no linear linear between x and y.

LinFit.Crunch() must be called before the return value is meaningful.

Usage:

Goodness = LinFit.CorrCoef()
     
Goodness REAL

The linear fit's correlation coefficient.
