Math and Trignometric - SUMXMY2 Function
Description
The SUMXMY2 function returns the sum of squares of differences of corresponding values in two arrays.
Syntax
SUMXMY2 (array_x, array_y)
Arguments
Argument | Description | Required/Optional |
---|---|---|
Array_x | The first array or range of values. | Required |
Array_y | The second array or range of values. | Required |
Notes
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, SUMXMY2 returns the #N/A error value.
The equation for the sum of squared differences is −
$$SUMXMY2 = \sum \left ( x-y \right )^2$$
