This longitudinal quantitative study investigates how organizational structure and the external environment impact VC firm survival. It examines how macroeco...

We propose a method to build trees and forests when the response is a non-homogeneous Poisson process with excess zeros, based on two forests. The first one...
BibTeX referenceSample size calculations for hierarchical Poisson and zero-inflated Poisson regression models
In biomedical research there is a growing interest in the use of hierarchical Poisson regression models. Although sample size calculations for testing pa...

Our main interest is the prediction of future events for recurrent event processes. We intend to build a Bayesian model, based on sound philosophical princip...

This paper provides some evidence on electricity--natural gas price interactions along with trade effects on electricity prices. The analysis helps to better...
BibTeX referencePower and Sample Size Calculations for Poisson and Zero-Inflated Poisson Regression Models
Although sample size calculations for testing a parameter in the Poisson regression model have been previously done, very little attention has been given to ...
BibTeX referenceEstimation from Aggregate Data
This work proposes a statistical methodology to handle aggregate data. Aggregate data arises in many fields such as medical science, ecology, social science,...
