Linear-testable and C-testable Nx~x Ny~ modified Booth multipliers
(Institution of Engineering and Technology (IET), 1996)
The testability of modified Booth multipliers is examined with respect to the cell fault model, an implementation-independent fault model. This is especially useful in design environments where the cell realisations are ...
Forecasting accuracy and system complexity
(Fontainebleau, France, 1995)
Accurate forecasts are essential for a great number of applications yet large errors and considerable uncertainty characterize most of our attempts for predicting the future. This article surveys empirical studies on ...

Exponential smoothing: The effect of initial values and loss functions on post-sample forecasting accuracy
(Elsevier Ltd, 1991-11)
This paper describes an empirical investigation aimed at measuring the effect of different initial values and loss functions (both symmetric and asymmetric) on the post-sample forecasting accuracy. The 1001 series of the ...
Accuracy measures: theoretical and practical concerns
The Notes section of the international Journal of Forecasting contains commentary on the theory and practice of forecasting in the form of communications to the journal such as research notes, teaching tips, practitioners’ ...
A Probabilistic Approach to Worst Case Scenarios

Long-term predictions are indispensable for planning and strategy. Yet little is known about their value, their limitations or the most appropriate way of making and using them. This paper examines these issues and proposes ...
ARMA Models and the Box–Jenkins Methodology
(John Wiley & Sons, Ltd., 1997-05)
The purpose of this paper is to apply the Box–Jenkins methodology to ARIMA models and determine the reasons why in empirical tests it is found that the post-sample forecasting the accuracy of such models is generally worse ...
