Usage notes

 * A biexponential equation/function/curve/model/distribution is the sum of two exponential ones. Specifically, a biexponential model has the form $$y=a_1 e^{b_1 t}+a_2 e^{b_2 t}$$
 * Biexponential time-series models commonly find use in pharmacokinetics.
 * In statistics, the biexponential distribution $$Y=p\lambda_1 e^{-\lambda_1\text{ } X}+(p-1)\lambda_2 e^{-\lambda_2\text{ } X}$$, where $$0<p<1$$, is a of two exponential distributions.
