Multiple Comparisons for Exponential Median Lifetimes with the Control Based on Doubly Censored Samples
2020
Mathematics
Preserved Fulltext
Under doubly censoring, the one-stage multiple comparison procedures with the control in terms of exponential median lifetimes are presented. ...
The upper bounds, lower bounds and two-sided confidence intervals for the difference between each median lifetimes and the median lifetime of the control population are developed. ...
Based on the doubly censored sample, Wu [8] proposed multiple comparisons with the average for exponential location parameters under heteroscedasticity. ...

A stochastic process is proposed, which is based on a comparison of the responses with a nonparametric quantile regression estimate under the null hypothesis. ...
We show that under certain straightforward and interpretable conditions, the marginal posterior for the parameter of interest converges in total variation to a negative exponential distribution, with parameters ...

This includes robust measures of location, scale, skewness, and heavytailedness of the response, conditionally on covariates. ...
In particular, we motivate why location, scale, skewness, and heavytailedness have order numbers 1, 2, (3,2), and (4,2) respectively and describe how a family of L-functionals, with different order numbers ...
For each 0 < p < 1, let Q(p | x) be an estimator of the conditional quantile (82), based on a sample of size n. ...
