Model Building for Semiparametric Mixtures
Ramani S. Pilla, Francesco Bartolucci, Bruce G. Lindsay
An important and yet difficult problem in fitting multivariate mixture models is determining the mixture complexity. We develop theory and a unified framework for finding the nonpa…
Inference in Perturbation Models, Finite Mixtures and Scan Statistics: The Volume-of-Tube Formula
Ramani S. Pilla, Catherine Loader
This research creates a general class of "perturbation models" which are described by an underlying "null" model that accounts for most of the structure in data and a perturbation…
Inference Under Convex Cone Alternatives for Correlated Data
Ramani S. Pilla
In this research, inferential theory for hypothesis testing under general convex cone alternatives for correlated data is developed. While there exists extensive theory for hypothe…
On large-sample estimation and testing via quadratic inference functions for correlated data
Ramani S. Pilla, Catherine Loader
Hansen (1982) proposed a class of "generalized method of moments" (GMMs) for estimating a vector of regression parameters from a set of score functions. Hansen established that, un…
