Natural Gas Prices Forecast Comparison--AEO vs. Natural Gas Markets

Wong-Parodi, Gabrielle; Lekov, Alex; Dale, Larry - 2008

This paper evaluates the accuracy of two methods to forecast natural gas prices: using the Energy Information Administration's ''Annual Energy Outlook'' forecasted price (AEO) and the ''Henry Hub'' compared to U.S. Wellhead futures price. A statistical analysis is performed to determine the...

Status of European appliance standards

Turiel, I.; Lebot, B. - 2008

The European Community (EC) recently commissioned a study of the impact of potential appliance standards on electricity consumption in the twelve EC nations. This study looks at refrigerators, freezers, dishwashers, clothes washers, and clothes dryers. The impact of minimum efficiency standards...

Insights into multivariate calibration using errors-in-variables modeling

Thomas, E.V. - 2009

A {ital q}-vector of responses, y, is related to a {ital p}-vector of explanatory variables, x, through a causal linear model. In analytical chemistry, y and x might represent the spectrum and associated set of constituent concentrations of a multicomponent sample which are related through...

Forecasting urban highway travel for year 2005

Miaou, Shaw-Pin; Rathi, A.K.; Southworth, F.; Greene, D.L. - 2008

As part of a study aimed at estimating suburban highway needs for year 2005, models were developed for forecasting daily vehicle miles of travel (DVMT) for urban areas and its distribution by highway functional class, urban location, and urban area size. A regression model combining both time...

An Analysis of the Price Elasticity of Demand for Household Appliances

Fujita, Kimberly; Dale, Larry; Fujita, K. Sydny - 2008

This report summarizes our study of the price elasticity of demand for home appliances, including refrigerators, clothes washers, and dishwashers. In the context of increasingly stringent appliance standards, we are interested in what kind of impact the increased manufacturing costs caused by...

Efficiency effects of variation in controlled experimental variables

Wendelbeger, J.R. - 2009

When a designed experiment is conducted, the exact levels of controlled experimental variables specified by the design may not be attainable. Two different types of situations can occur in which the actual settings of the design variables deviate from the target design settings. In one case, the...

The relationship between truck accidents and geometric design of road sections: Poisson versus negative binomial regressions

Miaou, Shaw-Pin - 2008

This paper evaluates the performance of Poisson and negative binomial (NB) regression models in establishing the relationship between truck accidents and geometric design of road sections. Three types of models are considered. Poisson regression, zero-inflated Poisson (ZIP) regression, and NB...

Common Assets: Asserting Rights to Our Shared Inheritance

Watt, Helen Payne - 2000

"Many of what we consider to be valuable natural assets existed for millennia without our ever being aware of their usefulness or value. For example, the capacity of the atmosphere to absorb pollution has only become useful to us in recent decades as the limits of that environmental service have...
