A lower bound for the Graver complexity of the incidence matrix of a complete bipartite graph

2011/3/24
We give an exponential lower bound for the Graver complexity of the incidence matrix of a complete bipartite graph of arbitrary size. Our result is a generalization of the result by Berstein and Onn (...
The Incidence and Wage Consequences of Home-Based Work in the United States, 1980–2000
Incidence Wage Consequences Home-Based Work United States
2016/3/8
This study documents the rapid growth in home-based wage and salary employment and the sharp decline in the home-based wage penalty in the United States between 1980 and 2000. These twin patterns, obs...
Inference in incidence, infection, and impact: Co-infection of multiple hosts by multiple pathogens

2009/9/24
A large literature concerns the epidemiology of single pathogens on single hosts. Yet in some environmental applications, such as fungal pathogens of forest tree seedlings, the “one host-one...
On the incidence-prevalence relation and length-biased sampling

For many diseases, logistic and other constraints often render large incidence
studies difficult, if not impossible, to carry out. This becomes a drawback,
particularly when a new incidence study is...
