WebRandom variables X & Y are bivariate normal if aX + bY has a normal distribution for all a,b∈R. X and Y are jointly normal if they can be expressed as X = aU + bV, and Y = cU + dV (Bertsekas & Tsitsiklis, 2002) If a and b are non-zero constants, aX + bY has a normal distribution (Johnson & Kotz, 1972). If X – aY and Y are independent and if ... WebThe y variables are normal, conditional on the x, so the raw y-values are a mixture of normals and a plot of just the y-values may not show normality even though they fit the assumption of being normal conditional on x. For diagnostics we generally use the residuals (because the conditional part has been mostly removed).
