SUMX2PY2

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.

• 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.
