二維正態分佈的引數與概率密度圖形

用Microsoft Mathematics繪製二維正態分佈的概率密度圖形,引數可以互動地調整。
N(μ1, μ2; σ1, σ2, ρ)

這裡寫圖片描述

μ1 = 1, μ2 = 1, σ1 = 0.49, σ2 = 0.49, ρ = 0
2d normal distribution

μ1 = 0, μ2 = 0, σ1 = 0.49, σ2 = 0.49, ρ = 0
2d normal distribution

μ1 = 0, μ2 = 0, σ1 = 0.334, σ2 = 0.49, ρ = 0
2d normal distribution

μ1 = 0, μ2 = 0, σ1 = 0.49, σ2 = 0.334, ρ = 0
2d normal distribution

μ1 = 0, μ2 = 0, σ1 = 0.49, σ2 = 0.49, ρ = -0.738


2d normal distribution

μ1 = 0, μ2 = 0, σ1 = 0.49, σ2 = 0.49, ρ = 0.738
2d normal distribution
