Performance of the Kenward-Project when the Covariance Structure is Selected Using AIC and BIC

Gomez, Elisa Valderas 1975- - 2004

to such analyses requires choosing a covariance structure. Information criteria, such as AIC and BIC, are often used by … KR adjustment method, incorporating the selection of the covariance structure using AIC and BIC. Performance of the AIC … analyze each simulated data set. Type I error rates from the best AIC and BIC models were always higher than target values …

Model selection criteria in the presence of missing data based on the Kullback-Leibler discrepancy

Sparks, JonDavid - 2009

An important challenge in statistical modeling involves determining an appropriate structural form for a model to be used in making inferences and predictions. Missing data is a very common occurrence in most research settings and can easily complicate the model selection problem. Many useful...

Noise Ratio As a Non-Nested Model Selection Tool.

Kurmanj, Agir - 2009

In this dissertation, we analyze whether the noise ratio statistic of Durlauf and Hall (1989), NRT, can be used as a non-nested model selection tool in a similar fashion to the Rivers and Vuong (2002) framework. For this purpose, we first show that, when scaled by the sample size T, NRT is...

Model Selection for Solving Kinematics Problems

Goh, Choon P. - 1990

There has been much interest in the area of model-based reasoning within the Artificial Intelligence community, particularly in its application to diagnosis and troubleshooting. The core issue in this thesis, simply put, is, model-based reasoning is fine, but whence the model? Where do the...

Semiparametric regression analysis of zero-inflated data

Liu, Hai - 2009

Zero-inflated data abound in ecological studies as well as in other scientific and quantitative fields. Nonparametric regression with zero-inflated response may be studied via the zero-inflated generalized additive model (ZIGAM). ZIGAM assumes that the conditional distribution of the response...

Nonparametric estimation for Levy processes with a view towards mathematical finance

Figueroa-Lopez, Enrique; Houdré, Christian - 2004

Nonparametric methods for the estimation of the Levy density of a Levy process X are developed. Estimators that can be writtenin terms of the "jumps" of X are introduced, and so are discrete-data based approximations. A model selection approach made up oftwo steps is investigated. The first step...

Transition economies and European integration: Role of the state and the banking sector

Wasiak, Radoslaw - 2002

Transition economies in Central and Eastern Europe have already completed the initial stabilization reforms and initiated the process of accession to European political and economic structures. Nonetheless, consensus exists that transition reforms are not complete. The state continues to exhibit...
