  • 10. 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:
