  • Cumulants (statistiques) — Dans la théorie des probabilités et en statistiques, une variable aléatoire X a une espérance mathématique μ = E(X) et une variance σ2 = E((X − μ)2). Ce sont les deux premiers cumulants : μ = κ1 et σ2 = κ2. Les cumulants κn sont définis par… …   Wikipédia en Français

  • Cumulant — In probability theory and statistics, the cumulants κn of a probability distribution are a set of quantities that provide an alternative to the moments of the distribution. The moments determine the cumulants in the sense that any two probability …   Wikipedia

  • Binomial type — In mathematics, a polynomial sequence, i.e., a sequence of polynomials indexed by { 0, 1, 2, 3, ... } in which the index of each polynomial equals its degree, is said to be of binomial type if it satisfies the sequence of identities:p n(x+y)=sum… …   Wikipedia
