squares_and_cubes/6

Auxiliary predicate for computing the skewness.

Compilation flags:
static
Template:
squares_and_cubes(List,Mean,Squares0,Squares,Cubes0,Cubes)
Mode and number of proofs:
squares_and_cubes(+list(number),+float,+float,-float,+float,-float) - one

squares_and_hypers/6

Auxiliary predicate for computing the kurtosis.

Compilation flags:
static
Template:

variance/6

Auxiliary predicate for computing the variance.

Compilation flags:
static
Template:
variance(List,Length0,Length,Mean,M20,M2)
