The Sensitivity Analysis of the Core Lower Head Molten Pool Model Based on Variance Decomposition
Journal of Nuclear Engineering and Radiation Science, 2020Abstract The lower head molten pool model is an important model for the in-vessel retention (IVR) effectiveness evaluation. It has the characteristics of complex relationship, many input parameters, and large uncertainty. The traditional local sensitivity analysis method has the disadvantages of large amount of calculation and low ...

The Accounting Review, 2006
Using the Vuolteenaho (2002) variance decomposition methodology, this study assesses the relative value relevance of cash flow, accrual, and expected return news on SEC and preliminary earnings filing dates, as measured by their contribution to the volatility of unexpected returns.

SUMMARY A factorization is given of the residual operator for nonorthogonal analysis of variance. It is interpreted geometrically in terms of the critical angles between the subspaces determined by the factors. The factorization determines a recursive procedure for analysis as described by Wilkinson (1970). Canonical components are defined and a method

Analysis of the Stochasticity of Mortality Using Variance Decomposition
2014We analyse the stochasticity in mortality data from the USA, the UK and Sweden, and in particular to which extent mortality rates are explained by systematic variation, due to various risk factors, and random noise. We formalise this in terms of a mixed regression model with a logistic link function, and decompose the variance of the observations into ...

Variance decomposition analysis of the demand for foreign money in Egypt
Journal of Economic Studies, 2001The demand for money is an important function of stabilization policies where such policies depend on the ability to manipulate the size of money supply in order to insulate real output from monetary disturbances. This paper investigates whether foreign money in Egypt should be included in transactions oriented measures of money supply.

Effects of crude oil shocks on the PPI system based on variance decomposition network analysis
Energy, 2019Abstract Previous studies have focused mainly on the price transmission from crude oil to producer price index (PPI). However, the PPI is an aggregate price index and consists of some producer price indices in different industrial sectors (sub-PPIs). Besides, there also exist transmissions relationships among sub-PPIs.

The october 1979 federal reserve policy shift: An analysis using variance decomposition
Atlantic Economic Journal, 1986Subsequent to the announced October 1979 policy shift, many economists voiced doubt about whether the Federal Reserve was sincerely committed to the execution of an NBR's targeting strategy. However, the charge that the central bank continued to accommodate as vigorously after the announced policy shift as before is not borne out by these results. Pre-

Despite the downward trend in fertility amongst the Chinese Malaysians, temporary fertility increases are noted in the Dragon years of 1976, 1988 and 2000. The paper therefore examines whether fertility is significantly influenced by zodiacal preferences, mainly the Year of the Dragon, for the Chinese Malaysians, a non-majority group within a ...

In manufacturing, powder mixing processes are vital for ensuring product quality. The mixing progress and efficiency are determined based on the fundamental convection and diffusion mechanisms. While mixers are believed to have a unique primary mixing mechanism, recent findings from our group have verified that the main mechanism can change as the ...

In this paper, we examine the relative importance of the cash flow and accruals components of earnings in explaining the variation in UK company equity returns, together with the extent to which these relationships vary by auditor quality. We use a multivariate time-series approach that can be reconciled to a log-linear theoretical valuation model and,
