SUMX2PY2

See Also

Returns the sum of the sum of squares of corresponding values in two arrays. The sum of the sum of squares is a common term in many statistical calculations.

Syntax

SUMX2PY2(array_x,array_y)

Array_x is the first array or range of values.

Array_y is the second array or range of values.

Remarks

The arguments should 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 array_x and array_y have a different number of values, SUMX2PY2 returns the #N/A error value.
The equation for the sum of the sum of squares is:
