Change of variables probability distribution

WebApr 24, 2024 · The probability density function ϕ2 of the standard bivariate normal distribution is given by ϕ2(z, w) = 1 2πe − 1 2 (z2 + w2), (z, w) ∈ R2. The level curves of ϕ2 are circles centered at the origin. The mode of the distribution is (0, 0). ϕ2 is concave downward on {(z, w) ∈ R2: z2 + w2 < 1} Proof.
