The Excel Sumx2py2 function returns the sum of the sum of squares of two supplied sets of values. I.e.

Equation for Sum of Sum of Squares

The syntax of the Sumx2py2 function is:

SUMX2PY2( array_x, array_y )

where the array arguments are two arrays of numeric values. These two arrays must be of equal length.

Note that, if any of the values supplied to the functions are non-numeric (including text representations of numbers), these values, and the corresponding value in the other array are ignored.
