Estimating Corn and Soybean Farm -Yield Distributions in Illinois
… most appropriate characterization of farm-level yield distributions. This dissertation investigates corn- and soybean-yield distributions at the farm level, expanding the existing literature by providing results based on unique farm-level yield data and by suggesting methodological improvements …

Risk in agriculture : a study of crop yield distributions and crop insurance
… information about the nature of historical crop yields is an important modeling input that helps farmers, agribusinesses, and governmental bodies in managing risk and establishing the proper policies for such things as crop insurance. Explicitly or implicitly, nearly all farm decisions relate in …

Evaluating yield models for crop insurance rating
… loss rates depend directly on underlying crop yield distributions. However, there still exists much debate about how to represent the underlying crop yield distributions. Using farm-level corn and soybean yields from 1972-2008, this study examines in-sample goodness-of-fit measures of both the …

Orbital effects on pitch angle diffusion of injected fast-ion beams in tokamaks
… ITER tokamak. Two methods are used to calculate distributions in the presence of orbits, one applying boundary conditions a posteriori and one a priori. In both cases an orbit average of the Fokker-Planck equation is taken, yielding a solution in velocity space variables velocity and pitch angle. …

Search for the production of quark-gluon plasma in e+e- collisions at [square root of] s = 91.2 GeV with Archived ALEPH LEP1 data
… qq̄ pair from the Z boson decay. The associated yield distributions in both analyses are in better agreement with predictions from the PYTHIA event generator than those from HERWIG, providing new insights into the hadronization modeling. These results serve as an important reference to the …

Production and Flow of Neutral Strange Particles in Ni+Ni Collisions at 1.93 AGeV
… signal processor. The slope parameter and yield distributions of the $K^0$ are found to agree with those of previously measured $K^+$. Comparisons to transport model calculations (UrQMD, IQMD) show that none of the models is able to consistently describe those distributions for both, $K^0$ …
