1 a type of structure of an organism or part of an organism in which a vertical cut through the axis in any of two or more planes produces two halves that are mirror images of each other.2  Compare bilateral symmetry. Trends. 2  a type of structure of an organism or part of an organism in which a vertical cut through the axis in any of two or more planes produces two halves that are mirror images of each other.
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.
Note that, as usual, there are an infinite number of possible gamma distributions because there are an infinite number of possible Î¸ and Î± values. That's, again, why this page is called Gamma Distributions (with an s) and not Gamma Distribution (with no s). Because each gamma distribution depends on the value of Î¸ and Î±, it shouldn't be surprising that the shape of the probability distribution changes as Î¸ and Î± change.
