Plan on 3 to 10 business days to send a USPS Certified Mail letter with First Class mail delivery. You can expedite delivery by upgrading to USPS Certified Mail with Priority Delivery. This is normally 2 or 3 day service.
Definition: Gamma distribution is a distribution that arises naturally in processes for which the waiting times between events are relevant. It can be thought of as a waiting time between Poisson distributed events. Probability density function: The waiting time until the hth Poisson event with a rate of change Î» is.
The general formula for the probability density function of the gamma distribution is. \( f(x) = \frac{(\frac{x-\mu}{\beta})^{\gamma - 1}\exp{(-\frac{x-\mu} {\beta}})} {\beta\Gamma(\gamma)} \hspace{.2in} x \ge \mu; \gamma, \beta > 0 \)
