This article describes the formula syntax and usage of the SUMXMY2 function in Microsoft Excel.
Description
Returns the sum of squares of differences of corresponding values in two arrays.
Syntax
SUMXMY2(array_x, array_y)
The SUMXMY2 function syntax has the following arguments:
-
Array_x Required. The first array or range of values.
-
Array_y Required. The second array or range of values.
Remarks
