There is a wide variety of dental alloys, ranging from nearly pure gold and conventional gold-based alloys to alloys based on silver, palladium, nickel, cobalt, iron, titanium, tin, and other metals (Table 1). The types of dental alloys have increased significantly since 1980s in order to change the market price of gold and palladium. Although gold alloys are the mate‐ rials of choice in this a...

We conduct evolutionary programming experiments to evolve artificial neural networks for forecast combination. Using stock price volatility forecast data we find evolved networks compare favorably with a naı̈ve average combination, a least squares method, and a Kernel method on out-of-sample forecasting ability—the best evolved network showed strong superiority in statistical tests of encompassi...

The day-ahead electricity market is closely related to other commodity markets such as the fuel and emission markets and is increasingly playing a significant role in human life. Thus, in the electricity markets, accurate electricity price forecasting plays significant role for power producers and consumers. Although many studies developing and proposing highly accurate forecasting models exist...

This addendum includes proofs that were deferred due to page constraints imposed on Oh and Özer (2012). For the sake of completeness, we provide all proofs including those that were published. In addition, the addendum provides complete analyses of the following extensions: (A1) The supplier incurs cost in obtaining a forecast update; (A2) the supplier sets the wholesale price; (A3) the supplie...

In their publication in Pharmacoeconomics Open, Akpinar et al. [1] reported the results of their review of methods for forecasting drug prices for economic evaluations. This was an interesting article, and I agreed with most of the conclusions. However, I disagree that prices forecast using the price of a close substitute on the same market may be more reliable. This conclusion may be biased be...
