SUMXMY2(x,y)

• $x$ and $y$ are the array of values.

Description

• This function gives the sum of squares of differences of corresponding values in $x$ and $y$.
• In $SUMXMY2(x,y)$, $x$ is the first array of real values and $y$ is the second array of real values.
• It is mostly common term in statistical calculations.
• This function is defined by: $SUMXMY2=\sum (x-y)^{2}$.
• 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 non-numeric or not a real number. 
    2. The arguments containing the error values or text that cannot be translated in to numbers.
    3. $x$ and <math>y<math> are having different number of values.
