RSQ

See Also

Returns the square of the Pearson product moment correlation coefficient through data points in known_y's and known_x's. For more information, see PEARSON. The r-squared value can be interpreted as the proportion of the variance in y attributable to the variance in x.

Syntax

RSQ ( known_y's , known_x's )

Known_y's is an array or range of data points.

Known_x's is an array or range of data points.

Remarks

The arguments must be either numbers or names, arrays, or references that contain numbers.

If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.

If known_y's and known_x's are empty or have a different number of data points, RSQ returns the #N/A error value.

The equation for the Pearson product moment correlation coefficient, r, is:
