A Framework for Model Validation
Easterling, R.G. - 2009
contexts, but success and acceptance require a convincing model validation. In general, model validation is understood to be a … comparison. This paper gives a statistical framework for the problem of model validation that is quite analogous to calibration …

Approaches to implementing deterministic models in a probabilistic framework
Talbott, D.V. - 2009
The increasing use of results from probabilistic risk assessments in the decision-making process makes it ever more important to eliminate simplifications in probabilistic models that might lead to conservative results. One area in which conservative simplifications are often made is modeling...

Fatigue reliability of wind turbine fleets: The effect of uncertainty of projected costs
Veers, P.S. - 2010
probability of individual component failure is sometimes interpreted as the percentage of components likely to fail, this … multiplying by the probability of individual component failure. However, more complicated cost models require a break down of how … many components are likely to fail. This break down enables the calculation of costs associated with various probability of …

Application of the bootstrap to the analysis of vibration test data
Hunter, N.F.; Paez, T.L. - 2010
Structural dynamic testing is concerned with estimation of system properties, including frequency response functions and modal characteristics. These properties are derived from tests on the structure of interest, during which excitations and responses are measured and Fourier techniques are...

Qualitative validation of emergency response procedures
Francis, A.A. - 2009
Emergency managers have come to recognize that there is a quintessential style of emergency response procedure development that must be guarded against. This style allows the definition of objectives to be decided upon apart from the problems posed by their implementation, and then permits the...

Global Liquidity, Risk Premiums and Growth Opportunities
Nicoló, Gianni De; Ivaschenko, Iryna V. - International Monetary Fund (IMF) - 2009
This paper constructs new indicators of liquidity for equity, bond and money markets in major advanced and emerging market countries, documents their evolution and comovements, and assesses the extent to which such measures are determinants of selected spreads and proxy measures of countries'...

Jamaica; Selected Issues
International Monetary Fund (IMF); International … - 2008
Economic outcomes in Jamaica have fallen short of the authorities’ objectives in recent years. As the government looks to reinvigorate its growth and debt reduction strategy, it is instructive to examine how exogenous shocks and other unanticipated developments can affect economic...

Methods for developing and validating survivability distributions
Williams, R.L. - 2008
A previous report explored and discussed statistical methods and procedures that may be applied to validate the survivability of a complex system of systems that cannot be tested as an entity. It described a methodology where Monte Carlo simulation was used to develop the system survivability...
