Expected exponent value
WebMar 19, 2024 · 3 Answers Sorted by: 1 Well, using the definition of Gamma function, we can see that E [ Y] = Γ ( a + 1) λ a. Next, using Prym's decomposition of Gamma function, we know that Γ ( a) = ∑ n = 0 ∞ ( − 1) n n! ( z + n) + ∫ 1 ∞ x a − 1 e − x d x. Hence, Γ ( a) has simple poles on negative integer.

WebThe table helps you calculate the expected value or long-term average. Add the last column x * P(x) to get the expected value/mean of the random variable X. E(X) = μ = ∑xP(x) = 0 + .5 + .6 = 1.1 The expected value/mean is 1.1. The men's soccer team would, on the average, expect to play soccer 1.1 days per week.
