WebThe Fisher-Darmois-Koopman-Pitman theorem says that for smooth nowhere vanishing probability densities, a finite dimensional sufficient statistic exists if and only if the densities are from an exponential family. This is a classical result for parameter estimation. It has also been proved for a limited class of random processes.

WebOct 24, 2008 · The theorems of Pitman and Koopman on laws of chance that yield sufficient statistics are extended to laws where the parameter or the observable, or both, may admit only a discrete set of values. WebIn the case when the support of the distribution does not depend on the unknown parameter $\theta, $ we can invoke the (Fréchet-Darmois-)Pitman-Koopman theorem, namely that the density of the observations is necessarily of the exponential family form, $$ \exp\{ \theta T(x) - \psi(\theta) \}h(x) $$ to conclude that, since the natural sufficient statistic $$ …

Koopmans' theorem states that in closed-shell Hartree–Fock theory (HF), the first ionization energy of a molecular system is equal to the negative of the orbital energy of the highest occupied molecular orbital (HOMO). This theorem is named after Tjalling Koopmans, who published this result in 1934. … See more While Koopmans' theorem was originally stated for calculating ionization energies from restricted (closed-shell) Hartree–Fock wavefunctions, the term has since taken on a more generalized meaning as a way of using orbital … See more The concept of molecular orbitals and a Koopmans-like picture of ionization or electron attachment processes can be extended to … See more Kohn–Sham (KS) density functional theory (KS-DFT) admits its own version of Koopmans' theorem (sometimes called the DFT-Koopmans' theorem) very similar in spirit to that of Hartree-Fock theory.
