The decomposition of Shannon's entropy and a confidence interval for beta diversity

, 2012
Beta diversity is among the most employed theoretical concepts in ecology and biodiversity conservation. Up to date, a self-contained definition of it, with no reference to alpha and gamma diversity, has never been proposed.

The Model Confidence Set

, 2010
The paper introduces the model confidence set (MCS) and applies it to the selection of models. A MCS is a set of models that is constructed such that it will contain the best model with a given level of confidence. The MCS is in this sense analogous to a

Pulling cost-effectiveness analysis up by its bootstraps: a non-parametric approach to confidence interval estimation.

Health Economics, 1997
The statistic of interest in the economic evaluation of health care interventions is the incremental cost effectiveness ratio (ICER), which is defined as the difference in cost between two treatment interventions over the difference in their effect ...

Bootstrap confidence intervals

Statistics & Probability Letters, 1988
Abstract Nonparametric confidence bounds are obtained for a wide class of statistics using bootstrap. These results improve the errors in the probability estimates of the confidence intervals over the ones obtained by the normal approximation theory unconditionally.

A Confidence Interval Procedure for Expected Shortfall Risk Measurement via Two-Level Simulation

Operational Research, 2010
We develop and evaluate a two-level simulation procedure that produces a confidence interval for expected shortfall. The outer level of simulation generates financial scenarios, whereas the inner level estimates expected loss conditional on each scenario.

Confidence Intervals II

1998
In the previous topic you began a study of the important and widely used technique of confidence intervals. These procedures use a sample statistic to estimate a population parameter with an interval of values and a certain confidence level. This topic asks you to continue this study by considering sample survey results and the connection between ...

A Confidence Interval for the Median Survival Time

, 1982
A nonparametric asymptotic confidence interval for the median survival time is developed for the case where data are subject to arbitrary right censoring. This is accomplished by inverting a generalization of the sign test for censored data. A simulation

Understanding confidence intervals

BMJ, 2014
Researchers investigated the effects of controlled cord traction in the third stage of labour on postpartum haemorrhage when carried out in a high resource setting. A randomised controlled trial study design was used. Control treatment was standard placenta expulsion (awaiting spontaneous placental separation before facilitating expulsion). The setting
