Multiple Comparisons for Exponential Median Lifetimes with the Control Based on Doubly Censored Samples

Shu-Fei Wu
2020 Mathematics  
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.  ...

A sequential distance-based approach for imputing missing data: Forward Imputation

Nadia Solaro, Alessandro Barbiero, Giancarlo Manzi, Pier Alda Ferrari
2016 Advances in Data Analysis and Classification  
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  ...

On the Use of L-functionals in Regression Models [article]

Ola Hössjer, Måns Karlsson
2022 arXiv   pre-print
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.  ...
