Deletion diagnostics are derived for the effect of individual observations on the estimated transformation of a time series. The paper uses the modified power transformation of Box and Cox to provide a parametric family of transformations. Inference about the transformation parameter is made...

A single outlier in a regression model can be detected by the effect of its deletion on the residual sum of squares. An equivalent procedure is the simple intervention in which an extra parameter is added for the mean of the observation in question. Similarly, for unobserved components or...

Forecasting is a critical component of project management. Project managers must beable to make reliable predictions about the final duration and cost of projects startingfrom project inception. Such predictions need to be revised and compared with theproject's objectives to obtain early...

Diese Dissertation umfasst sowohl einen theoretisches als auch einen empirischen Beitrag zur Analyse der Messung der gesamten Faktorproduktivität (TFP). Das erste Kapitel inspiziert die bestehende Literatur über die häufigsten Techniken der TFP Messung und gibt einen Überblick über deren...

This study estimates liquidity premiums using the recently developed Liu (2006) measure within a multifactor capital asset pricing model (CAPM) including size premiums and a time-varying parameter model for the North African emerging markets of Algeria, Egypt, Morocco and Tunisia. The evidence...

Seven adaptive approaches to post-processing wind speed forecasts are discussed and compared. 48-hour forecasts are run at horizontal resolutions of 7 km and 3 km for a domain centred over Ireland. Forecast wind speeds over a two year period are compared to observed wind speeds at seven synoptic...

In the framework of the intertemporal asset allocation problem, this dissertation focuses on the modelling of inflation risk and its impact on intertemporal asset allocation strategies. The contributions of this dissertation to the current literature are as follows.First, in considering...
