The product multinomial distribution
WebbRecall that the density function of a univariate normal (or Gaussian) distribution is given by p(x;µ,σ2) = 1 √ 2πσ exp − 1 2σ2 (x−µ)2 . Here, the argument of the exponential function, … WebbFollowing the strategy of our previous examples, we rewrite the multinomial distribution as follows: p(x π) = M! x1!x2!···xm! exp (XK k=1 xk logπk).

In summary, assuming that the data is ordinal means that there is a certain ordering of the discrete data. The specific ordering is determined by a latent continuous distribution. The data for the ordinal approach needs the same setup as for the nominal approach.
