SUMX2MY2(x,y)
- and are the array of values.
Description
- This function gives the sum of the difference of squares of corresponding values in and .
- In is the first array of real values and is the second array of real values.
- This function is defined by .
- The arguments can be be either numbers or names, array,constants or references that contain numbers.
- Suppose the array contains text,logical values or empty cells, like that values are not considered.
- This function will give the result as error when
1. Any one of the argument is nonnumeric or not a real number. 2. The arguments containing the error values or text that cannot be translated in to numbers. 3. x and y are having different number of values.
Examples
x={29,71,10,16} y={16,50,8,14} SUMX2MY2(B1:B4,C1:C4) = null
