Asset returns and their volatilities.
Estimation and modeling of volatilities.
Mixtures with constant relative volatilities are investigated.
Leafcutter ants (genus Atta) have alarm pheromones consisting of four components with different volatilities.
They find that the organic vapours driving initial growth have extremely low volatilities.
"With his leadership, we can deal with the inevitable risks and volatilities arising out of the transition".
There is currently no futures market for virtual currencies, so no way to hedge against possible volatilities in their value.
Systems with lower relative volatilities perform best with the heat pump option, while systems with higher relative volatilities perform better with heat integration.
Process parameters such as relative volatilities between reactants, relative volatilities between products, column pressure, activation energies, and pre-exponential factors are varied to seek possible generalization.
The methods assume constant relative volatilities and constant molar flow rates within each distillation section.
Our model links the univariate volatilities with the correlations via a hidden stochastic decision tree.
