The parameter λ represents the expected number of goals in the game or the long-run average among all possible such games. The expression x! stands for x factorial, i.e., x! = 1 ∗ 2 ∗ 3 ∗ ⋯ ∗ x. P ( X = x) or P (x) is the probability that X (the random variable representing the unknown ...

Refers to finding the best values for model’s parameters given some outcomes/data. NettetThis means one of the μ’s is equal to a data-point x_n. In the limit of a variance tending to 0, the likelihood term will behave like a delta function. So maximizing likelihood isn’t a …
