... sometimes provide a rather poor approximation of entropy. There are two main reasons for this. First, finite- sample estimators of higher-order cumulants are highly sensitive to outliers: their values ... (prove this first!). Fur- thermore, use the fact that any expression involving a third-order monomial of the 122 INFORMATION THEORY higher-order cumulants is infinitely smaller than terms i...
