The only memoryless continuous probability distribution is the exponential distribution, shown in the following proof: [9] First, define S ( t ) = Pr ( X > t ) {\displaystyle S(t)=\Pr(X>t)} , also known as the distribution's survival function .
(This formula is sometimes called the Hartley function.) This is the maximum possible rate of information that can be transmitted with that alphabet. (The logarithm should be taken to a base appropriate for the unit of measurement in use.) The absolute rate is equal to the actual rate if the source is memoryless and has a uniform distribution.
In probability theory and statistics, an inverse distribution is the distribution of the reciprocal of a random variable. Inverse distributions arise in particular in the Bayesian context of prior distributions and posterior distributions for scale parameters .
The mathematical model consists of a transition probability that specifies an output distribution for each possible sequence of channel inputs. In information theory, it is common to start with memoryless channels in which the output probability distribution only depends on the current channel input. A channel model may either be digital or analog.
Degenerate distribution: A deterministic or fixed service time. M/D/1 queue: E k: Erlang distribution: An Erlang distribution with k as the shape parameter (i.e., sum of k i.i.d. exponential random variables). G: General distribution: Although G usually refers to independent service time, some authors prefer to use GI to be explicit. M/G/1 ...

Georges noted that fluoride levels in the water supply are dictated at a local level, and many counties have chosen not to implement them. Federal health agencies can make recommendations but ...
a parallel extension of the C programming language that supports efficient access to a global address space on current distributed memory multiprocessors. It retains the "small language" character of C and supports careful engineering and optimization of programs by providing a simple, predictable cost model. [1] Development of Split-C appears ...
