Shannon measure
Webb17 feb. 2015 · Shannon's formula C = 1 2 log (1+P/N) is the emblematic expression for the information capacity of a communication channel. Hartley's name is often associated with it, owing to Hartley's rule: counting the highest possible number of distinguishable values for a given amplitude A and precision ±Δ yields a similar expression C′ = log (1+A/Δ). WebbThe Shannon entropy can measure the uncertainty of a random process. Rolling element machinery without failure tends to generate a more random signal, and the machine with failure usually tends to have a more deterministic …

WebbThe Shannon–Hartley theorem states the channel capacity , meaning the theoretical tightest upper bound on the information rate of data that can be communicated at an … The Shannon index has been a popular diversity index in the ecological literature, where it is also known as Shannon's diversity index, Shannon–Wiener index, and (erroneously) Shannon–Weaver index. The measure was originally proposed by Claude Shannon in 1948 to quantify the entropy (hence Shannon entropy, related to Shannon information content) in strings of text. The idea is that the more letters there are, and the closer their proportional abundances in the string of inter…
Webb10 okt. 2010 · I can't seem to find a well established and simple statistical measure of uniformity in occurrence datasets in the presence of zero-valued categories. I've looked at Shannon's entropy which seems to be the closest but the problem is that it can't tell me anything about variables which have no occurrences in them. Webb4 juli 2015 · If you calculate Shannon-Weiner index in such case, it will come to close to zero and Simpson index will turn out to be one or close to one.

WebbThe Shannon information can be interpreted as quantifying the level of "surprise" of a particular outcome. As it is such a basic quantity, it also appears in several other settings, such as the length of a message needed to transmit the event given an optimal source coding of the random variable.
