Abstract
Cenzētu izdzīvošanas datu vidējā izdzīvošanas ilguma novērtēšanai literatūrā atrodamas vairākas metodes. Darbā aplūkota Džekknaifa metode Kaplāna-Meiera integrālim, Kaplāna-Meiera novērtētājs izdzīvošanas datiem, B.Efrona pieeja vidējā izdzīvošanas ilguma noteikšanai cenzētiem datiem, kā arī apskatīta datorprogrammas RStudio pieejamā pakotne jackknifeKME. Apskatīti dažādu novērtētāju rezultāti vidējam izdzīvošanas ilgumam simulētiem datiem un reālu datu piemēriem.
Several methods can be found in literature to estimate the mean survival time of censored survival data. In this thesis the application of the Jackknife method for the Kaplan-Meier integral, the Kaplan-Meier estimator for survival data, B.Efron’s approach to determint the average survival time for censored data, as well as the jackknifeKME package available from the computer programm Rstudio has been viewed. The results of different estimators for the average survival time for simulated data and real data examples are considered.
