What distribution does X/(X+Y), follow, when X and Y are gamma distributed. Prove that the R.V is independent of (X+Y) up vote 0 down vote favorite. What distribution does the following r.v follow: X/(X+Y) Xâ¼Gamma(a,1) Yâ¼Gamma(b,1) and the variables are independent.
Best Answer: If y is a function of x (Ex: y = 2x + 1), then x is the independent variable and y the dependent variable. This is the case most of the time. If x is a function of y (Ex: x = 2y - 1), then y is the independent variable and x is the dependent variable. Source(s): Son GokÅ« on the Flying Nimbus Â· 7 years ago. Thumbs up.
