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. ...
At last, one practical example is provided to illustrate the proposed procedures. ...
Based on the doubly censored sample, Wu [8] proposed multiple comparisons with the average for exponential location parameters under heteroscedasticity. ...

This includes robust measures of location, scale, skewness, and heavytailedness of the response, conditionally on covariates. ...
In this setting, the distribution of the response is treated parametrically or nonparametrically, and the response variable is either censored/truncated or not. ...
For each 0 < p < 1, let Q(p | x) be an estimator of the conditional quantile (82), based on a sample of size n. ...
