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.
The phrase y is a function of x means that the value of y depends upon the value of x, so: 1  y can be written in terms of x (e.g. y = 3x 2  ). If f(x) = 3x, and y is a function of x (i.e. y = f(x) ), then the value of y when x is 4 is f(4), which is found by replacing xs by 4s .
