Distribution Theory — cumulants in terms of raw moments

If krk_r and μr′\mu_r' denote respectively the rthr^{\text{th}} cumulant and the rthr^{\text{th}} moment about origin zero of a distribution, then which of the following statements are correct? I. k1=μ1′k_1 = \mu_1' II. k2=μ2′−μ1′2k_2 = \mu_2' - \mu_1'^2 III. k3=μ3′−3μ2′μ1′+2μ1′3k_3 = \mu_3' - 3\mu_2'\mu_1' + 2\mu_1'^3 Select the answer using the code given below:
