Improved bootstrap point and confidence interval estimation of the incremental cost-effectiveness ratio (ICER)

New Technical Efficiency Estimates with Improved Bootstrap Confidence Interval Coverage

Bootstrap confidence intervals on fixed-effects efficiency estimates from finite-sample panel data models exhibit low coverage probabilities, because the traditional estimate involves a "max" operator that induces a finite sample bias. Attempts to bootstrap confidence intervals for the traditional estimate have focused on correcting bias. Rather than addressing this bias at the bootstrap stage,...

Bootstrap estimate of the variance and confidence interval of kappa.

Point and Interval Estimation for the Burr Type III Distribution

In this paper, we study the estimation problems for the Burr type III distribution based on a complete sample. The maximum likelihood method is used to derive the point estimators of the parameter. An exact confidence interval and an exact joint confidence region for the parameters are constructed. Two numerical examples with real data set and simulated data, are presented to illustrate the met...

Interval Appendectomy: Finding the Breaking Point for Cost-Effectiveness.

BACKGROUND Patients with phlegmonous appendicitis can be managed nonoperatively, yet debate continues about the need for interval appendectomy (IA), given the low risk of recurrence or neoplasm. We sought to determine for which patient age interval appendectomy is cost-effective. METHODS Using TreeAge software, a cost-effectiveness model was developed. Two strategies were compared, IA and no ...

Bootstrap confidence interval estimates of the bullwhip effect

This paper introduces the confidence interval estimate for measuring the bullwhip effect, which has been observed across most industries. Calculating a confidence interval usually needs the assumption about the underlying distribution. Bootstrapping is a non-parametric, but computer intensive, estimation method. In this paper, a simulation study on the behavior of the 95% bootstrap confidence i...
