Splet18. dec. 2013 · 0. If you have the Statistic toolbox you can simply use exprnd much like you use rand: r = exprnd (mu); where the size of r will be the size of the mean, mu, or. r = exprnd (mu,m,n); where mu is a scalar mean, and m and n are the size of your desired output. If you type edit exprnd, you'll see that the code is virtually identical to that kindly ... SpletWe can state this formally as follows: P(X > x + a X > a) = P(X > x). If X is exponential with parameter λ > 0, then X is a memoryless random variable, that is P(X > x + a X > a) = P(X > x), for a, x ≥ 0. From the point of view of waiting time until arrival of a customer, the memoryless property means that it does not matter how long you ...

Splet14. apr. 2024 · Example 4.5. 1. A typical application of exponential distributions is to model waiting times or lifetimes. For example, each of the following gives an application of an exponential distribution. X = lifetime of a radioactive particle.

SpletWe will see that sub-exponential distributions and sub-gaussian distributions are closely related. First, note that any sub-gaussian distribution is sub-exponential. Second, the square of a sub-gaussian random variable is sub-exponential: Lemma 3 (2.7.6 in V). A random variable Xis sub-gaussian if and only if X2 is sub-exponential. Moreover ...
