1/5/10 Continuous Uniform Dist. The uniform distribution is probably the simplest continuous distribution. Its distribution in general form is: fX(x) = 1/(b-a) The Uniform distribution has two
1/5/10 Example Suppose we know that exactly one arrival occurred between time 4 and time 13 in a Poisson process. Let X be the arrival time. How is X distributed? Since arrivals in the Poisson process can occur at any time, the time will be Uniform(4,13). The mean, variance and CDF are relatively easy to find: x b a dx a b / ( ) - a b - x a dx a b ) /( 1 a x

The Normal Distribution The Normal distribution is probably the most famous and most commonly used distribution. It is also know as the Gaussian distribution after Gauss who is generally credited with its invention (although it seems that De Moivre may have derived it first). The Central Limit Theorem
