This paper is concerned with time series forecasting in the presence of a large number of predictors. The results are of interest, for instance, in macroeconomic and financial forecasting where often many potential predictor variables are available. Most of the current forecast methods with many...

Macroeconomic forecasting is not an easy task, in particular if future growth rates are forecasted in real time. This paper compares various methods to predict the growth rate of US Industrial Production (IP) and of the Composite Coincident Index (CCI) of the Conference Board, over the coming...

Forecasting with many predictors is of interest, for instance, in macroeconomics and finance. This paper compares two methods for dealing with many predictors, that is, principal component regression (PCR) and principal covariate regression (PCovR). The forecast performance of these methods is...

Various ways of extracting macroeconomic information from a data-rich environment are compared with the objective of forecasting yield curves using the Nelson-Siegel model. Five issues in factor extraction are addressed, namely, selection of a subset of the available information, incorporation...

Port of Rotterdam Authority is a publicly owned but corporatized port development company. In 2004, this organisation was transformed from a municipal department to an independently operating company. The corporatisation intended to improve the overall performance of the port of Rotterdam....

Pre-election polls can suffer from survey effects. For instance, individuals taking part in the poll may become more aware of the upcoming election so that they become more inclined to vote. Such effects cause biases in forecasted outcomes of elections. We propose a simple methodology that takes...

Safety management and risk profiling to identify substandard ships are of importance to the shipping industry. Whereas current methods rely heavily on detention risk and flag state performance, we extend the risk assessment by considering various risk dimensions and by evaluating a wide range of...

The effectiveness of safety inspections has been analysed from various angles, but until now, relatively little attention has been given to translate risk reduction into incident cost savings. This paper quantifies estimated cost savings based on port state control inspections and industry...

Global trade depends for a large part on maritime transport, and safe ships are needed not only to protect precious cargo but also to prevent environmental damage. Flag state and port state authorities spend much effort in ship safety inspections to ensure a minimum safety level and to prevent...

Since the early 1990's, the International Maritime Organization (IMO) has designated fourteen sea areas as Particular Sensitive Sea Areas (PSSA) that enjoy special protection because of their various important attributes and vulnerability to potential harm by increasing shipping activities. The...
