Webb12 okt. 2024 · Cov ( X 1, Y) = Cov ( X 1, Y − X 1) + Cov ( X 1, X 1) = Var [ X 1] ≠ 0. So X 1 and Y are not independent. To compute the probability distribution of ( X 1, Y) you will want to condition on X 1. It is intuitive that for fixed x, f Y ∣ X 1 ( y ∣ x) will be the probability density function of a Gamma distribution with parameters n − 1 ... WebbGammaDistribution [α, β, γ, μ] represents a continuous statistical distribution defined over the interval and parametrized by a real number μ (called a "location parameter"), two positive real numbers α and γ (called "shape parameters") and a positive real number β (called a "scale parameter"). The parameter μ determines the horizontal location of the …
