Probability density function - In mathematics, a probability density function (pdf) serves to represent a probability distribution in terms of integrals. A probability density function is non-negative everywhere and its integral from −∞ to +∞ is equal to 1.
Density of states - Density of states (DOS) is a property in statistical and condensed matter physics that quantifies how closely packed energy levels are in some physical system. It is often expressed as a function g(E) of the internal energy E, or a function g(k) of the wavevector k.
Local-density approximation - The local-density approximation, (LDA), is a density functional model in physics, which approximates the electron correlation energy with respect to the local electron density. In this sense, local means that, within the LDA model, the electron correlation at any point in space is a function of the electron ...
Probability mass function - In probability theory, a probability mass function (abbreviated pmf) gives the probability that a discrete random variable is exactly equal to some value. A probability mass function differs from a probability density function in that the values of the latter, defined only for continuous random variables, are not probabilities; rather, its integral over a set of possible values of the random variable is a probability.
