Optimal diet selection by white-tailed deer: Balancing reproduction with starvation risk [PDF]

open access: yesEvolutionary Ecology, 1992
Summary Energy intake rates of wintering deer vary over time because of variation in the abundance and quality of their natural foods. Accordingly, there is a chance that energy requirements will not be satisfied in a feeding period. This is especially critical because deer are reproductive during winter; hence selecting diets to minimize the risk of ...

CONDITIONAL VAR USING GARCH-EVT APPROACH WITH OPTIMAL TAIL SELECTION

open access: yesProceedings of the 10th Economics & Finance Conference, Rome, 2018
Accurate risk prediction plays a key role in effective risk management process. A conditional GARCH-EVT approach combines Extreme Value Theory and GARCH methodology and it allows us to estimate Value at Risk with high accuracy. The approach requires to pre-specify a threshold indicating distribution tails. In this paper we use an optimal tail selection
