Jelaskan Some properties of cumulants dari Cumulant dalam bahasa sunda

The first cumulant is shift-equivariant; all of the others are shift-invariant.    To state this less tersely, denote by κn(X) the nth cumulant of the probability distribution of the random variable X.  The statement is that if c is constant then κ1(X + c) = κ1(X) + c and κn(X + c) = κn(X) for n≥ 2, i.e., c is added to the first cumulant, but all higher cumulants are unchanged.
