Using different combinations of culture, development and openness to international trade, we test the variability in the incidences of corruption at different stages of development or in other words the non-linearities in the relationship between corruption and development. We employ formal threshold model developed by Hansen (2000), and unlike the existing literature, we find that: (1) non-lin...

In this paper, we develop a Bayesian approach to estimate a Cox proportional hazards model that allows a threshold in the regression coefficient, when some fraction of subjects are not susceptible to the event of interest. A data augmentation scheme with latent binary cure indicators is adopted to simplify the Markov chain Monte Carlo implementation. Given the binary cure indicators, the Cox cu...

This paper points out an important source of inefficiency in Smola and Schölkopf's sequential minimal optimization (SMO) algorithm for support vector machine (SVM) regression that is caused by the use of a single threshold value. Using clues from the KKT conditions for the dual problem, two threshold parameters are employed to derive modifications of SMO for regression. These modified algorithm...

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...
