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:
