Modeling Model Uncertainty [PDF]

open access: yesJournal of the European Economic Association, 2002
Recently there has been a great deal of interest in studying monetary policy under model uncertainty. We develop new methods to analyze different sources of uncertainty in one coherent structure, which is useful for policy decisions. We show how to estimate the size of the uncertainty based on time series data, and how to incorporate this uncertainty ...

An Entropic Approach for Pair Trading in PSX

open access: yesEntropy, 2023
The perception in pair trading is to recognize that when two stocks move together, their prices will converge to a mean value in the future. However, finding the mean-reverted point at which the value of the pair will converge as well as the optimal ...

Large Modeling Uncertainty in Projecting Decadal Surface Ozone Changes Over City Clusters of China

open access: yesGeophysical Research Letters, 2023
Climate policies will affect future surface ozone pollution in China. Here, we simulate changes in summertime ozone across China by 2030 under four emission scenarios reflecting different levels of climate action.

Fatigue design sensitivities of large monopile offshore wind turbines

open access: yesWind Energy, 2022
The input for fatigue analyses of offshore wind turbines is typically chosen based on design values provided by design standards. While this provides a straightforward design methodology, the contribution of different input parameters to the uncertainty ...

Nested Models and Model Uncertainty [PDF]

open access: yesThe Scandinavian Journal of Economics, 2015
AbstractUncertainty about the appropriate choice among nested models is a concern for optimal policy when policy prescriptions from those models differ. The standard procedure is to specify a prior over the parameter space, ignoring the special status of submodels (e.g., those resulting from zero restrictions).

On the Combination of Physical Parameterization Schemes for Tropical Cyclone Track and Intensity Forecasts in the Context of Uncertainty

open access: yesJournal of Advances in Modeling Earth Systems, 2023
The selection of physical parameterization schemes for tropical cyclone (TC) forecasts has required a substantial amount of effort. In general, the evaluation of physical parameterization schemes and their combined performance was based solely on the ...
