Density is “random” in the x-y plane. When take a slice parallel to x-y, you get a circle. When r = .75, Σ is not a diagonal . Density is not random in x-y plane. There is a linear tilt (ie., density is concentrated on a line). When you take a slice you get an ellipse that’s tilted. church lewiston idaho
