Econ Definitions

Stochasticity - portraying a stochastic tendency. Example: You thoughts display stochasticity that is alarming.

Heteroskedastastic - Amazingly heteroskedastic data. Example: Those results are heteroskedastastic! Opposite: Homoskedastastic - Fantastically homoskedastic data.

(For readers not in the know, homoskedasticity is characterized by regression residuals whose variance does not depend on any exogenous variables. In other words, the conditional variance of the residual given X is constant).

One of these words is made up, but that doesn't make the other one any less fun to use and say.
