Expert subject Probability date May 2011 In the study of stochastic process es, Palm calculus , named after Swedish teletraffic engineering teletrafficist Conny Palm , is the study of the relationship between probability probabilities conditioned on a specified event and time average probabilities. A Palm probability or Palm expected value expectation , often denoted math P 0 cdot math or math E 0 cdot math , is a probability or expectation conditioned on a specified event occurring at time 0. Little s formula A simple example of a formula from Palm calculus is Little s law math L lambda W math , which states that the time average number of users L in a system is equal to the product of the rate math lambda math at which users arrive and the Palm average waiting time W that a user spends in the system. That is, the average W gives equal weight to the waiting time of all customers, rather than being the time average of the waiting times of the customers currently in the system . Feller s paradox An important example of the use of Palm probabilities is Feller s paradox, often associated with the analysis of an Pollaczek Khinchine formula M G 1 queue . This states that the time average time between the previous and next points in a point process is greater than the expected interval between points. The latter is the Palm expectation of the former, conditioning on the event that a point occurs at the time of the observation. This paradox occurs because large intervals are given greater weight in the time average than small intervals. PASTA A useful result in Palm calculus is that Poisson arrivals see time averages PASTA . That means that, if the event being conditioned on is a point in a Poisson process independent of the process being observed , then the distinction between ... first Jean Yves year 2007 title Understanding the simulation of mobility models with Palm calculus ... calculus Category Telecommunication theory probability stub ... more details
