SUMX2PY2 function

This article describes the formula syntax and usage of the SUMX2PY2 function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

Description

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)

The SUMX2PY2 function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

  • Array_x    Required. The first array or range of values.
  • Array_y    Required. 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:
