Let x and y have a bivariate normal distribution and suppose that x and y both have
Question:
Let x and y have a bivariate normal distribution and suppose that x and y both have mean 0 and variance 1, so that their marginal distributions arc standard normal and their joint density is
Show that if the correlation coefficient between x and y is p, then that between x2 and y2 is p2.
Transcribed Image Text:
p(x, y) = {2π √(1-p²)}" ¹ exp{-1 (x² − 2pxy + y²)/(1 − p²)}. .

I am currently a Ph.D. student in Immunology. Here, I used to design experiments based on the knowledge I have in cell biology, Molecular Biology, Immunology, Biochemistry, and Molecular Biology. I used to teach my students with practical examples and touch of my experimental knowledge. This not only helps them to easily grasp the concept but also leads to the visualization of the situation.
