The distribution constant (or partition ratio) (KD) is the equilibrium constant for the distribution of an analyte in two immiscible solvents. In chromatography...

continuous probability distribution that has a constant failure rate. The quantile function (inverse cumulative distribution function) for Exp(λ) is...

The Planck constant, or Planck's constant, denoted by h {\textstyle h} , is a fundamental physical constant of foundational importance in quantum mechanics:...

the distinction between  X  being constant or almost surely constant is unimportant, since the cumulative distribution function  F(x)  of  X  does not depend...

εi is the energy of that state, and a constant kT of the distribution is the product of the Boltzmann constant k and thermodynamic temperature T. The...

theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable...

empirically determined constants, and later showed that, expressed as an energy distribution, it is the unique stable distribution for radiation in thermodynamic...

In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number...

The Boltzmann constant (kB or k) is the proportionality factor that relates the average relative thermal energy of particles in a gas with the thermodynamic...

essentially a mixture of a discrete distribution (constant 0) and a continuous distribution (a truncated Gaussian distribution with interval ( 0 , ∞ ) {\displaystyle...

theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence...

density function, which gives the standard normal distribution. In Bayes' theorem, a normalizing constant is used to ensure that the sum of all possible...

gamma distribution is a versatile two-parameter family of continuous probability distributions. The exponential distribution, Erlang distribution, and...

probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] or (0, 1) in...

subexponential distribution. Furthermore, the constant K {\displaystyle K} is the same in the definitions (1) to (5), up to an absolute constant. So for example...
