The function SumOfSquaredNumCells adds the squares of all data cells within a specified range of cells which are neither marked as csNAN, nor as csUndefined and which belong to either interval or ratio scaled variables (that is, all cells which contain "real" numbers). The range of the data table elements to be summed is determined by the parameters LowRow, LowCol, HighRow, and HighCol. If any of these parameters receives an invalid value, this value is automatically adjusted to the nearest boundary value (either 1 or NrOfColumns / NrOfRows). The function returns the sum of the squared numeric data cells within the specified range. The variable parameter NumData returns the number of data points used for the calculation (i.e. the number of numeric data cells within the specified range).
