Bu çalışmada yeni bir yaşam testi metodu olan yarı-zamanlı operatörlü
ilerleyen tür tip-I aralık sansürleme tanıtılmıştır. Weibull dağılımı
parametreleri için en çok olabilirlik tahminleri elde edilmiştir. Tahminlere
ait ortalama yan değerlerini, ortalama varyanslarını ve hata kareler
ortalamasını (MSE) araştırmak için simülasyon çalışması yapıldı. Elde edilen
sonuçlar, ilerleyen tür tip-I aralık sansürlü örneklem, part-time operatörlü
sansürlü örneklem ve tam örneklem durumları için karşılaştırılmıştır.

Statistical Estimation for the Weibull Distribution Under Progressive Type-I Interval Censoring with Part-Time Operator

Öz

In this study, a new life testing method called “progressive type-I
interval censoring with part time operator” is introduced. We obtained the
maximum likelihood estimators for parameters of Weibull distribution. A
simulation study is conducted to investigate the mean biases, mean variances
and MSE (Mean Squared Error)'s of estimates. The results are compared for
sampling progressive type-I interval censored data, part-time operator and
complete data.
