English

Etymology

bi- +? exponential

Adjective

1. (mathematics) Having two summed exponential terms.

Derived terms

• biexponentiality

Noun

biexponential (plural biexponentials)

Usage notes

A biexponential equation/function/curve/model/distribution is the sum of two exponential ones. In specific, a biexponential model has the form

${\displaystyle y=a_{1}e^{-b_{1}{\text{ }}t}+a_{2}e^{-b_{2}{\text{ }}t}}$

• Biexponential time-series models commonly find use in pharmacokinetics.
• In statistics, the biexponential distribution ${\displaystyle Y=p\lambda _{1}e^{-\lambda _{1}{\text{ }}X}+(p-1)\lambda _{2}e^{-\lambda _{2}{\text{ }}X}}$, where ${\displaystyle 0<p<1}$, is a sum of two exponential distributions.
