A Factor Model for Euro-area Short-term Inflation Analysis

Lenza, Michele; Warmedinger, Thomas - In: Jahrbücher für Nationalökonomie und Statistik 231 (2011) 1, pp. 50-62

Summary This paper develops a factor model for forecasting inflation in the euro area. The model can handle variables with different timeliness, sample size and frequency. We show that the forecasts based on the factor model outperform naïve random walk forecasts, a hard to beat benchmark for...

The effect of missing data on wind resource estimation

Coville, Aidan; Siddiqui, Afzal; Vogstad, Klaus-Ole - In: Energy 36 (2011) 7, pp. 4505-4517

missing data, which can bias energy resource estimates if the missingness is systematic. We address this issue by considering … the influence of missing data due to icing of equipment during the winter on the wind resource estimation for a potential … account for the impact on the expected revenue from a wind turbine constructed at the site. While missing data due to icing …

A closer examination of three small-sample approximations to the multiple-imputation degrees of freedom

Wagstaff, David A.; Harel, Ofer - In: Stata Journal 11 (2011) 3, pp. 403-419

Incomplete data is a common complication in applied research. In this study, we use simulation to compare two approaches to the multiple imputation of a continuous predictor: multiple imputation through chained equations and multivariate normal imputation. This study extends earlier work by...

Scoring rules and survey density forecasts

Boero, Gianna; Smith, Jeremy; Wallis, Kenneth F. - In: International Journal of Forecasting 27 (2011) 2, pp. 379-393

This article provides a practical evaluation of some leading density forecast scoring rules in the context of forecast surveys. We analyse the density forecasts of UK inflation obtained from the Bank of England’s Survey of External Forecasters, considering both the survey average forecasts...

Tradeoffs in Trade Data

Boehmer, Charles R.; Jungblut, Bernadette M.E.; Stoll, … - In: Conflict Management and Peace Science 28 (2011) 2, pp. 145-167

replacing some missing data with estimated values tends to inflate the effects of trade in conflict models, although the effects …
