Since Quenouille’s influential work on multiple time series, much progress has been made towards the goal of parameter reduction and model fit. Relatively less attention has been paid to the systematic evaluation of out-of-sample forecast performance of multivariate time series models. In this paper, we update the hog data set studied by Quenouille (and other researchers who followed him). We r...

This paper considers the implications of the permanent/transitory decomposition of shocks for identi…cation of structural models in the general case where the model might contain more than one permanent structural shock. It provides a simple and intuitive generalization of the in‡uential work of Blanchard and Quah (1989), and shows that structural equations for which there are known permanent s...

background: municipal solid waste (msw) is the natural result of human activities. msw generation modeling is of prime im­portance in designing and programming municipal solid waste management system. this study tests the short-term pre­diction of waste generation by artificial neural network (ann) and principal component-regression analysis. methods: two forecasting techniques are presented in...

The surface code scheme for quantum computation features a 2d array of nearestneighbor coupled qubits yet claims a threshold error rate approaching 1% [1]. This result was obtained for the toric code, from which the surface code is derived, and surpasses all other known codes restricted to 2d nearest-neighbor architectures by several orders of magnitude. We describe in detail an error correctio...

the aims of this research were to estimate of genetic parameters for pre-weaning traits and lamb survival in iran-black sheep. for this purpose 6344 records for birth weight (bw) and lamb survival (ls) and 5264 records for weaning weight (ww), average daily gain (adg) and kleiber ratio (kr) were available, which collected by abbasabad animal breeding and rearing station, over the period from 19...

Using the consumer theory approach as suggested by Habibullah (2009), this study aims to shed new light on monetary authority by incorporating advertising expenditure, a variable that has been neglected in the past, into study of the money demand function in Indonesia. In addition, different measurements of monetary aggregates (simple-sum and Divisia money) have been used in the estimation to p...

Using a vector error-correction model, I explore the short-run dynamics and long-run linkages between financial reform and the mobilization of domestic saving in Morocco. In the short run, financial depth (volume of intermediation) is shown to have a positive influence on private saving, while increases in real interest rates have a negative impact. The effectiveness of financial intermediation...
