NettetThis 5 -variate joint distributions is also a multivariate normal distribution in which the mean vector is just the concatenation ( μ 1, μ 2) T of the two mean vectors and the covariance matrix is. Σ = [ Σ 11 0 0 Σ 22]. Thus, the joint distribution of Y 11 − Y 13 + Y 22 and Y 21 − Y 12 is a bivariate normal distribution which can be ...

The density function describes the relative likelihood of a random variable at a given sample. If the value is high around a given sample, that means that the random variable will most probably take on that value when sampled at random.. … black and white tights adult
