The Volume-of-Tubes Formula: Computational Methods and Statistical Applications (2005)

Loader, Catherine

The volume-of-tube formula was first introduced by Hotelling (1939), to solve significance of terms in nonlinear regression models. Since this pioneering paper, there has been significant work on...

Inference in Perturbation Models, Finite Mixtures and Scan Statistics: The Volume-of-Tube Formula (2005)

Pilla, Ramani S., Loader, Catherine

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 that accounts for...

A New Technique for Finding Needles in Haystacks: A Geometric Approach to Distinguishing Between a New Source and Random Fluctuations (2005)

Pilla, Ramani S., Loader, Catherine, Taylor, Cyrus

We propose a new test statistic based on a score process for determining the statistical significance of a putative signal that may be a small perturbation to a noisy experimental background. We...

On large-sample estimation and testing via quadratic inference functions for correlated data (2005)

Pilla, Ramani S., Loader, Catherine

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, under certain...

Fast and robust signaling overload control (2001)

Sneha Kasera, José Pinheiro, Catherine Loader, Mehmet Karaul, Adiseshu Hari, Tom Laporta

Telecommunication switches implement overload controls to maintain call throughput and delay at acceptable levels during periods of high load. Existing work has mostly focused on controls under...

Sneha Kasera, José Pinheiro, Catherine Loader, Mehmet Karaul, Adiseshu Hari, Tom Laporta

Confidence bands in generalized linear models (2000)

Loader, Catherine, McCormick, William P., Sun, Jiayang

Generalized linear models (GLM) include many useful models. This paper studies simultaneous confidence regions for the mean response function in these models. The coverage probabilities of these...

Testing for order-restricted hypotheses in longitudinal data

Ramani S. Pilla, Annie Qu, Catherine Loader

In many biomedical studies, we are interested in comparing treatment effects with an inherent ordering. We propose a "quadratic score test" (QST) based on a quadratic inference function for detecting...
