The Mean function returns the average of the values of the
argument variables which have nonmissing values. Examples:
avg=Mean(x, y, z);
avg=Mean(of x1-x10);
avg=Mean(of x y z);
The first and last example assign avg the average of the variables
x, y, and z which have nonmissing values. Note the
differences in syntax. The last example returns the average of the variables among
x1, ..., x10 which have nonmissing values.
