Let this solution be x1 u1(y1, y2) and x2 u2(y1, y2).

That is, let Y1 h1(X1, X2) where X1 and X2 are discrete random variables with joint distribution fX1 X2 1x1, x2 2. We want to find the probability distribution of Y1, say, fY1 1 y1 2. To do this, we de ne a second function Y2 h2(X1, X2) so that the one-to-one correspondence between the points (x1, x2) and (y1, y2) is maintained, and we use the result in Equation S5-2 to nd the joint probability distribution of Y1 and Y2. Then the distribution of Y1 alone is found by summing over the y2 values in this joint distribution. That is, fY1 1 y1 2 is just the marginal probability distribution of Y1, or fY1 1 y1 2 EXAMPLE S5-2 a fY1Y2 1 y1, y2 2Bar Code barcode library with .netUsing Barcode recognizer for .NET Control to read, scan read, scan image in .NET applications.Consider the case where X1 and X2 are independent Poisson random variables with parameters X1 X2. 1 and 2, respectively.

Now to use Equation S5-2 we need to de ne a second function Y2 h2(X1, X2). Let this function be Y2 X2. Now the solutions for x1 and x2 are x1 y1 y2 and x2 y2.

Therefore, we have shown that the sum of two independent Poisson random variables with parameters 1 and 2 has a Poisson distribution with parameter 1 2. We now consider the situation where the random variables are continuous. Let Y with X continuous and the transformation is one to one. h(X),Suppose that X is a continuous random variable with probability distribution fX (x). The function Y h(X) is a one-to-one transformation between the values of Y and X so that the equation y h(x) can be uniquely solved for x in terms of y. Let this solution be x u(y). The probability distribution of Y is fY 1 y2 fX 3u1 y2 4 0 J 0 (S5-3)where J u ( y) is called the Jacobian of the transformation and the absolute value of J is used. Equation S5-3 is shown as follows.
