After defining the structure to a signal detection scheme, this dissertation describes and addresses some of the unresolved issues associated with its use when the interference encountered is impulsive. The alpha-stable (alpha-S) family of distributions is used as a model of this interference...

Crop insurance performance and 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 test statistics are widely used in health and medicine related surveys however little regard is usually given to their statistical power. This paper investigates the simulated power of five categorical goodness-of-fit test statistics used to analyze health and medicine survey...

Generated crop insurance rates depend critically on the distributional assumptions of theunderlying crop yield loss model. Using farm level corn yield data from 1972-2008, we revisitthe problem of examining in-sample goodness-of-fit measures across a set of flexibleparametric, semi-parametric,...

We propose simple sequential calibration for an asset price model driven by piecewise Lévy processes, for which simulation methods and Greeks formulas are available. The proposed methods are easy to implement and consist of fitting a sequence of Lévy processes to a return series such that they...

Since the publication of Keynes' “General Theory of Employment, Interest, and Money” in 1936 many new ideas and solution concepts for macroeconomic problems emerged, disappeared, and were combined in order to appropriately describe macroeconomic phenomena. Nowadays, New Keynesian frameworks...

Using many moment conditions can improve efficiency but makes the usual generalized method of moments (GMM) inferences … inaccurate. Two-step GMM is biased. Generalized empirical likelihood (GEL) has smaller bias, but the usual standard errors are … under many weak moments. In addition, we introduce a jackknife GMM estimator, but find that GEL is asymptotically more …
