This paper introduces an iterative method to estimate the cointegrating vectors in the error correction models. The method provides the asymptotically efficient estimators for the cointegrating vectors if iterated once or more. If it is iterated until convergence, we may obtain the maximum likelihood estimator by Johansen. For all values of 1 ≤ k ≤ ∞, the k-step iterative estimators are asympto...
We present a method for solving Poisson and heat equations with discontinuous coefficients in twoand three-dimensions. It uses a Cartesian cutcell/embedded boundary method to represent the interface between materials, as described in Johansen & Colella (1998). Matching conditions across the interface are enforced using an approximation to fluxes at the boundary. Overall second order accuracy is...
The present paper tests for the validity of long-run purchasing power parity (PPP) for seventeen European economies in transition. Analysis is performed following the methodological suggestions expressed in recent studies for PPP. Longrun PPP is initially tested for each economy vis-a-vis the US, using the Johansen cointegration methodology and then for the whole set of countries using the Lars...
In this paper we introduce Basic Elements, a new way of automating the evaluation of text summaries. We show that this method correlates better with human judgments than any other automated procedure to date, and overcomes the subjectivity/variability problems of manual methods that require humans to preprocess summaries to be evaluated. This is demonstrated on DUC 2005 peer systems and peer-pr...
This document describes opportunistic encryption (OE) as designed and implemented by the Linux FreeS/WAN project. OE uses the Internet Key Exchange (IKE) and IPsec protocols. The objective is to allow encryption for secure communication without any pre-arrangement specific to the pair of systems involved. DNS is used to distribute the public keys of each system involved. This is resistant to pa...
The two tasks in the TREC2005 Robust track were as follows: given a set of topics, A) predict their ranking according to average precision; and B) improve the effectiveness of their ad hoc retrieval, in particular the weakest topics and if possible with the help of what has been found in task A. The difference from last year is that the test collection (ACQUAINT) is different from the training ...
