Koster, Maurice - 2008

We focus on the Moulin-Shenker cost sharing rule as a natural extension of the serial rule to multi-service facilities where services are personalized. We show that it is the unique regular rule that is compatible with scale invariance and self consistency

A Comparative Study of Test Procedures uses in Assessing the Forecasting Ability of Linear Models with Applications to Crop Yield Data

Linardis, Apostolis; Panaretos, John - Volkswirtschaftliche Fakultät, … - 1998

The choice of the appropriate linear model before this can be used for planning and decision making, has been the … candidate models. In the present paper an evaluation scheme of the predictability of a linear model based on a function of the … function, the predictability of a linear model is tested. Considering the ratio of such functions for two linear models, the …

Non-linear Threshold Relationships between Inflation and Nominal Returns: A Time Series Approach to 39 Different Countries

Barnes, Michelle L. - School of Economics, University of Adelaide - 1998

A linear null relationship between nominal returns and inflation is tested against threshold alternatives using quarterly and monthly data for 39 different countries. These threshold alternatives and the linear nulls are then estimated to unover the nature of linear and threshold relationships...

Travel Trends Using the Puget Sound Panel Survey: A Generalized Estimating Equations Approach

Yee, Julie; Niemeier, Debbie - Institute of Transportation Studies (ITS), University … - 1998

This paper examines longitudinal mode use trends using four waves of the Puget Sound Transportation Panel. The analysis is conducted using generalized estimating equations for model estimation. In addition to examining mode use frequencies over time, we also consider mode use trends conditioning...

Interindividual and interoccasion variability of toxicokinetic parameters in population models

Selinski, Silvia; Urfer, Wolfgang - 1998

The determination of toxicokinetic parameters is an essential component in the risk assessment of potential harmful chemicals. It’s a first step to analyse the processes which are involved in the development of DNA adducts and might therefore lead to the development of cancer. The complete...

Fitting of Threshold Models for Time Series

Schlittgen, Rainer - 1998

One of the most important parametric nonlinear time series models is the (self exciting) threshold autoregressive model. The TAR model was introduced by Tong/Lim (1980). There are some extensions to this class of models, namely smooth transition threshold autoregressive model. Other nonlinear...

Forecasting Asymmetric Unemployment Rates

Rothman, Philip; Stock, James H. - 1998

Asymmetric behavior has been documented in post-war quarterly U.S. unemployment rates. This suggests that improvement over conventional linear forecasts may be possible through use of nonlinear time series models. In this paper an out-of-sample forecasting competition is carried out for a set of...

Standardization of Process Norms in Baker's Yeast Fermentation through Statistical Models in Comparison with Neural Networks

Das, Prasun; Bera, Sasadhar - In: Journal of Applied Statistics 34 (2007) 5, pp. 511-527

Achieving consistency of growth pattern for commercial yeast fermentation over batches through addition of water, molasses and other chemicals is often very complex in nature due to its bio-chemical reactions in operation. Regression models in statistical methods play a very important role in...
