SUMX2PY2 function

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:
