Nonparametric Tests for Censored Data [EPUB ebook] 

Ajutor

This book concerns testing hypotheses in non-parametric models.
Generalizations of many non-parametric tests to the case of
censored and truncated data are considered. Most of the test
results are proved and real applications are illustrated using
examples. Theories and exercises are provided. The incorrect use of
many tests applying most statistical software is highlighted and
discussed.
