Share. For this The multinomial distribution arises from an experiment with the following properties: a fixed number \(n\) of trials; each trial is independent of the others; each trial has \(k\) mutually exclusive and exhaustive possible outcomes, denoted by \(E_1, \dots, E_k\) 1. The natural logarithm of the multinomial coefficient separates from $\sum_{i=1}^{m} x_{i} ln(p_{i}),$ and maximum likelihood estimation only considers the latter due to argmax. The probability of getting y 1 of outcome 1, y 2 of outcome 2, …, and y K of outcome K out of a total of N trials is Multinomially distributed. We often write X˘M k(n;p 1; ;p k) to denote a multinomial distribution.seulav owt naht erom ot ,)eruliaf dna sseccus sa hcus( seulav owt ylno stimda hcihw ,noitubirtsid laimonib eht fo noitazilareneg a ,scitsitats ni ,noitubirtsid laimonitlum … halmuj :n :samE )!k x * … !2 x * !1 x( / )k x k p * … * 2 x 2 p * 1 x 1 p( * !n = satilibaborP . μ : rata-rata σ2 : variansi xi : hasil sukses ke- pi : peluang ke- G.
