Calculates the A statistic for the average absolute deviation for two or more groups. Note: This function is not meant to be called by the user, but it is called by AAD1.

1	CalcAAD1(y, r = 0, weights = FALSE)

`y`	Matrix of cases (rows) by scores (column 1) and group codes (column 2) (matrix).
`r`	Vector of proportions (default = 0, represents equal proportions) (vector).
`weights`	Weight of each case. Set to TRUE to weight cases; if so, column 3 contains case weights (default = FALSE).

`a`	The A statistic.
