Modelling stock market performance of firms as a function of the quality and quantity of intellectual property owned

Chauhan, Lokendra Pratap Singh - 2007

This thesis attempts to analyze a part of the big and complex process of how intellectualproperty ownership and technological innovation influence the performance of firms andtheir revenues. Here I analyze a firm's stock market performance as a function of thequantity and quality of intellectual...

Multiple Imputation for Measurement Error Correction Based on a Calibration Sample.

Guo, Ying - 2010

In much of applied statistics variables of interest are measured with error. In particular, regression with covariates that are subject to measurement error requires adjustment to avoid biased estimates and invalid inference. We consider two aspects of this problem. Detection Limits (DL) arise...

Statistical Inverse Problems on Graphs with Application to Flow Volume Estimation in Computer Networks.

Singhal, Harsh - 2009

Estimation of flow volumes in computer networks involves the use of data that are either highly aggregated or fairly noisy. We address several conceptual and practical aspects of the use of such data for flow volume estimation in this work. The results presented are often of general statistical...

A Scaled Linear Mixed Model for Multiple Outcomes

Lin, Xihong; Ryan, Louise; Sammel, Mary; Zhang, Daowen; … - 2000

We propose a scaled linear mixed model to assess the effects of exposure and other covariates on multiple continuous outcomes. The most general form of the model allows a different exposure effect for each outcome. An important special case is a model that represents the exposure effects using a...

Two Stochastic Multidimensional Choice Models for Marketing Research

Carroll, J. Douglas; Soete, Geert; DeSarbo, Wayne S. - 1990

Two recently developed probabilistic multidimensional models for analyzing pairwise choice data are introduced, discussed in terms of their differential properties, and extended in several ways. The first one, the wandering vector model, was originally suggested by Carroll [12] and extended by...

Flexible Estimation of Differences in Treatment-Specific Recurrent Event Means in the Presence of a Terminating Event

Pan, Qing; Schaubel, Douglas E. - 2009

In this article, we consider the setting where the event of interest can occur repeatedly for the same subject (i.e., a recurrent event; e.g., hospitalization) and may be stopped permanently by a terminating event (e.g., death). Among the different ways to model recurrent/terminal event data,...
