PURPOSE The purpose of this study was to develop a regression model to estimate the heart rate at the lactate threshold (HRLT) and the heart rate at the ventilatory threshold (HRVT) using the heart rate threshold (HRT), and to test the validity of the regression model. METHODS We performed a graded exercise test with a treadmill in 220 normal individuals (men: 112, women: 108) aged 20-59 year...

This paper provides evidence for a significant relation between international financial markets’ integration and output volatility. In the framework of a threshold model, it is shown empirically that this relation depends on country’s financial risk. Financial risk indicates a country’s ability to pay its official, commercial and trade debts. In countries with low financial risk, financial open...

Mozambique A Non-Parametric Extension to the Threshold Model Bjorn Van Campenhout One of the main drawbacks of current methods to measure market integration is the assumption of constant transaction costs. In this paper, we propose a non-parametric extension to the commonly used threshold models, allowing us to estimate transaction costs in a more flexible way. We illustrate the method using we...

Dynamic task allocation is an essential aspect in modelling ant behaviour. In this paper, we propose a new (abstract) model for dynamic task allocation of agents that combines a nested layered architecture with a threshold mechanism. We apply this new model to achieve flexible ant behaviour. This serves the dual purpose of validating the abstract model, and providing a concrete model for adapti...

We investigate the behavior of a threshold model for the spreading of fads and similar phenomena in society. The model is giving the fad dynamics and is intended to be confined to an underlying network structure. We investigate the whole parameter space of the fad dynamics on three types of network models. The dynamics we discover is rich and highly dependent on the underlying network structure...

|r(xi + ex)− r(xi)| ≤M2 ‖ex‖ , |fx(xi + ex)− fx(xi)| ≤M3 ‖ex‖ for some positive number M1,M2, and M3. ri (xi), E(si|xi), fx(xi) are p-th order differentiable and the p-th order derivatives are bounded.

one of the models that can be used to study the relationship between boolean random sets and explanatory variables is growth regression model which is defined by generalization of boolean model and permitting its grains distribution to be dependent on the values of explanatory variables. this model can be used in the study of behavior of boolean random sets when their coverage regions variation...

Objectives. To better understand the consequences of whole or partial reliance on test scores as a screening mechanism for college or university admissions or for job placement or promotion. Methods. We introduce a simple hurdles/threshold model to study one particular mechanism that has been recently proposed to generate a ‘‘compromise’’ between race-normed or gender-normed standards for accep...
