Cost-effectiveness of nivolumab plus ipilimumab versus lenvatinib or sorafenib for unresectable hepatocellular carcinoma in China: a modeling study with price threshold analysis [PDF]

Frontiers in Pharmacology
BackgroundNivolumab plus ipilimumab has demonstrated survival benefits as first-line therapy for unresectable hepatocellular carcinoma (HCC). However, the high treatment cost may limit its economic value in China.

Troublesome or Threshold? : the experience of difficult concepts in prosthetics [PDF]

, 2012
This thesis explores what is experienced as difficult, and potentially threshold, concepts in prosthetics. Prosthetics and orthotics education is an under-researched area and this research assists in filling this gap.

A Bayesian nonlinearity test for threshold moving average models [PDF]

, 2010
We propose a Bayesian test for nonlinearity of threshold moving average (TMA) models. First, we obtain the marginal posterior densities of all parameters, including the threshold and delay, of the TMA model using Gibbs sampler with the Metropolis ...

Threshold effects in cointegrating relationships [PDF]

, 2006
In this paper, we introduce threshold-type nonlinearities within a single-equation cointegrating regression model and propose a testing procedure for testing the null hypothesis of linear cointegration vs. cointegration with threshold effects.

A mixed distribution to fix the threshold for Peak-Over-Threshold wave height estimation [PDF]

, 2022
Modelling extreme values distributions, such as wave height time series where the higher waves are much less frequent than the lower ones, has been tackled from the point of view of the Peak-Over-Threshold (POT) methodologies, where modelling is based on

SAR and Social-Media-Based Change Detection With Dual-Threshold Fusion for Flood Inundation Mapping

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
As one of the most destructive natural disasters, floods are increasingly frequent and severe due to urban development and population growth. The threshold-based method is widely acknowledged as an effective approach for detecting flood extent in ...

Statistical evaluation of absolute change versus responder analysis in clinical trials

Acta Materia Medica, 2022
In clinical trials, the primary analysis is often either a test of absolute/relative change in a measured outcome or a corresponding responder analysis.
