Analysis of Middle Censored Data with Exponential Lifetime Distributions
Recently Jammalamadaka and Mangalam (2003) introduced a general censoring scheme called the “middle-censoring” scheme in non-parametric set up. In this paper we consider this middle censoring scheme when the lifetime distribution of the items are exponentially distributed and the censoring mechanism is independent and non-informative. In this set up, we derive the maximum likelihood estimator a...
متن کاملRegression analysis of mean quality-adjusted lifetime with censored data.
In clinical trials of chronic diseases such as acquired immunodeficiency syndrome, cancer, or cardiovascular diseases, the concept of quality-adjusted lifetime (QAL) has received more and more attention. In this paper, we consider the problem of how the covariates affect the mean QAL when the data are subject to right censoring. We allow a very general form for the mean model as a function of c...
متن کاملAnalysis of interval-censored data with Weibull lifetime distribution
In this work the analysis of interval-censored data, with Weibull distribution as the underlying lifetime distribution has been considered. It is assumed that censoring mechanism is independent and non-informative. As expected, the maximum likelihood estimators cannot be obtained in closed form. In our simulation experiments it is observed that the Newton-Raphson method may not converge many ti...

متن کاملCensored Data and Truncated Distributions
We detail the basic theory for regression models in which dependent variables are censored or underlying distributions are truncated. The model is extended to models for counts, sample selection models, and models hazard models for duration data. Entry level theory is presented for the practitioner. We then describe a few of the recent, frontier developments in theory and practice. To appear as...
