  • Tutorial on methods for interval-censored data and their implementation in R

    Gomez, G.   Calle, M L.   Oller, R.   Langohr, K.  

    Interval censoring is encountered in many practical situations when the event of interest cannot be observed and it is only known to have occurred within a time window. The theory for the analysis of interval-censored data has been developed over the past three decades and several reviews have been written. However, it is still a common practice in medical and reliability studies to simplify the interval censoring structure of the data into a more standard right censoring situation by, for instance, imputing the midpoint of the censoring interval. The availability of software for right censoring might well be the main reason for this simplifying practice. In contrast, several methods have been developed to deal with interval-censored data and the corresponding algorithms to make the procedures feasible are scattered across the statistical software or remain behind the personal computers of many researchers. The purpose of this tutorial is to present, in a pedagogical and unified manner, the methodology and the available software for analyzing interval-censored data. The paper covers frequentist non-parametric, parametric and semiparametric estimating approaches, non-parametric tests for comparing survival curves and a section on simulation of interval-censored data. The methods and the software are described using the data from a dental study.

  • Late-time spectral evolution of the Type II supernova 1990E in NGC 1035*

    Gomez, G.   Lopez, R.  

    We present low-resolution spectra obtained from 5 to 11 months after the discovery of the Type II supernova 1990E in NGC 1035. We analyse the evolution of the Halpha feature and discuss the late-time luminosity-powering source through the evolution of the Halpha flux. Whatever the SN 1990E photometric subclass, the shape of the Halpha profile in these spectra (a relatively weak absorption trough) and its appearance in a near-maximum spectrum (very broad emission with secondary narrow emission components superimposed) are reminiscent of the characteristics of some peculiar events reported by Schlegel or even of some supernova events that have been preceded by a mass-loss episode (such as Supernova 1979C), and this Halpha profile seems to be different from those displayed by some typical Type II-P supernovae (such as 1969L, 1973R or 19861) at the same phases. The evolution of the Halpha flux points to extra late-time luminosity relative to that derived from a radioactive model. According to Chugai's models, this extra energy could be released in the interaction between the supernova ejecta and the pre-supernova wind.
