Model error (or ambiguity) and its estimation, with particular application to loss reserving

Taylor, Greg; Mc Guire, Gráinne - In: Risks : open access journal 11 (2023) 11, pp. 1-28

two of these components, and their estimation, are well understood, but less so model error. Model error itself is … considered in two parts: one part that is capable of estimation from past data (internal model error), and another part that is … not (external model error). Attention is focused here on internal model error. Estimation of this error component is …

Escape from model-land

Thompson, Erica L.; Smith, Leonard A. - 2019

Both mathematical modelling and simulation methods in general have contributed greatly to understanding, insight and forecasting in many fields including macroeconomics. Never-theless, we must remain careful to distinguish model-land and model-land quantities from the real world. Decisions taken...

Interaction between Macroeconomics Variables and IBOVESPA, Brazilian Stock Market Index

Santos, Allan Silveira dos; Neto, Angelo Rondina; … - In: Transnational Corporations Review 5 (2013) 4, pp. 81-95

This paper analyzes the relations between macroeconomic variables and the Brazilian stock market index, the Ibovespa, from January of 2001 to December of 2011, using a Vector Error Correction model (VEC). The main results showed that the Ibovespa reacts negatively to impulses in the exchange...

Kriging Models That Are Robust With Respect to Simulation Errors

Den Hertog, Dick; Siem, A.Y.D. - Tilburg University, Center for Economic Research - 2007

In the field of the Design and Analysis of Computer Experiments (DACE) meta-models are used to approximate time-consuming simulations. These simulations often contain simulation-model errors in the output variables. In the construction of meta-models, these errors are often ignored....

Making Forecasts for Chaotic Processes in the Presence of Model Error

Danforth, Christopher M - 2006

model error in forecasts.The first method is inspired by Leith (1978) who proposed a statistical method to account for model … than unperturbed solutions of L. This is true even when the perturbations are significantly smaller than the model error. …
