Inference in Mixed Proportional Hazard Models with K Random Effects

Horny, Guillaume - 2010

A general formulation of Mixed Proportional Hazard models with K random effects is provided. It enables to account for a population stratified at K different levels. We then show how to approximate the partial maximum likelihood estimator using an EM algorithm. In a Monte Carlo study, the...

Random Coefficient Logit Model for Large Datasets

H. Mireles, Carlos - 2010

We present an approach for analyzing market shares and products price elasticities based on large datasets containing aggregate sales data for many products, several markets and for relatively long time periods. We consider the recently proposed Bayesian approach of Jiang et al [Jiang, Renna,...

The choice between fixed and random effects models : some considerations for educational research

Clarke, Paul; Crawford, Claire; Steele, Fiona; … - 2010

We discuss fixed and random effects models in the context of educational research and set out the assumptions behind the two approaches. To illustrate the issues, we analyse the determinants of pupil achievement in primary school, using data from the Avon Longitudinal Study of Parents and...

Correlation, Hierarchies, and Networks in Financial Markets

Tumminello, Michele - 2010

We discuss some methods to quantitatively investigate the properties of correlation matrices. Correlation matrices play an important role in portfolio optimization and in several other quantitative descriptions of asset price dynamics in financial markets. Specifically, we discuss how to define...
