The Statistics 'Linear regression' screen presents the the following calculations based on
the statistics values:
- Slope of a best-fit straight line through the x/y coordinates.
- Y-intercept of the best-fit line.
- Val is the current value in the main screen display (for reference).
- Est X calculates the X-value of a point on the best-fit line where
the Y-value is equal to 'Val'.
- Est Y calculates the Y-value of a point on the best-fit line where
the X-value is equal to 'Val'.
- The 'correlation' calculates how well the best-fit line actually fits
the statistics data. This doesn't work at present.
