Abel differential equation: A non-linear ordinary differential equation typically expressed in the form x˙ = A (t)x³ + B (t)x², where A (t) and B (t) are functions that modulate the non-linearity.

A computationally tractable, easily interpretable linear simultaneous equations model for dummy endogenous variables is presented. The reduced form of the model is more general than the multivariate ...
