SKEWNESS(argument-1,argument-2,argument-3<,...argument-n>)
|
-
argument
-
specifies a numeric constant, variable,
or expression.
At least three non-missing arguments are required. Otherwise,
the function returns a missing value. If all non-missing arguments have equal
values, the skewness is mathematically undefined. The SKEWNESS function returns
a missing value and sets _ERROR_ equal to 1.
The argument list can consist of a variable list, which is preceded
by OF.
