Dynkin’s (Bull. Amer. Math. Soc. 3 (1980) 975–999) seminal work associates a multidimensional transient symmetric Markov process with a multidimensional Gaussian random field. This association, known as Dynkin’s isomorphism, has profoundly influenced the studies of Markov properties of generalized Gaussian random fields. Extending Dykin’s isomorphism, we study here a particular...
The detection and determination of clusters has been of special interest among researchers from different fields for a long time. In particular, assessing whether the clusters are significant is a question that has been asked by a number of experimenters. In Fuentes and Casella (2009), the authors put forth a...
Over the past decade, it has come to light that many published scientific findings cannot be reproduced. This has led to the replication crisis in science. Many researchers feel that they can no longer trust much of what they read in scientific journals, and the public is becoming ever more...
Multiple linear regression was used to develop equations for 12-,
24-, and 36-hour surface wind forecasts for the wind energy site at
Goodnoe Hills. Equations were derived separately for warm and cool
seasons. The potential predictors included LFM II model output, MOS
surface wind forecasts extrapolated from surrounding stations, pressure...
Probabilistic inference using Bayesian networks is now a well-established approach for reasoning under uncertainty. Among many e ciency-driven tech- niques which have been developed, the Optimal Factoring Problem (OFP) is distinguished for presenting a combinatorial optimization point of view on the problem. The contribution of this thesis is to extend...
Significant figures have been a nebulous area in the physical sciences. The results of a literature survey, and of a questionaire distributed among the Chemistry Department faculty at Oregon State University, revealed widely differing interpretations regarding the proper role of significant figures. The present study has a two-fold nature. First...
Structural engineered wood manufacturers need a quantitative measurement technique to determine the ratio of wood to adhesive failure in their shear specimens. Visual estimation of percent wood failure has long stood as an extremely subjective quality control approach according to ASTM D5266 – Standard Practice for Estimating the Percentage of...
It is the purpose of this study to examine some statistically-oriented considerations which may facilitate
portfolio selection policies. Many of the preliminary
topics discussed parallel and extend the notions of
W. J. Baumol, H. M. Markowitz, and W. F. Sharpe.
The crux of the study introduces a quadratic programming
algorithm...
