HyperexponentialDistribution
HyperexponentialDistribution[{
1, ..., m}, {
1, ..., m}]
represents an m-phase hyperexponential distribution with phase probabilities 
and rates 
.
Details
- HyperexponentialDistribution is also known as a mixed exponential or parallel m-phase exponential distribution.
- An m-phase hyperexponential distribution can be interpreted as having m servers in parallel where the i
server has service rate 
and is picked with probability 
. - The probability density for value
in an exponential distribution is 
for 
, and is zero for 
. - HypoexponentialDistribution allows
to be any non-negative numbers such that 
and 
to be any positive real numbers. - HyperexponentialDistribution can be used with such functions as Mean, CDF, and RandomVariate.
