Left-truncated data with age as time scale: an alternative for survival analysis in the elderly population. J Gerontol A Biol Sci Med Sci. 1998;53(5): M337-M343.Lamarca R, Alonso J, Gomez G, Munoz A. Left-truncated data with age as time scale: an alternative for survival analysis in...
When start times are known, left-truncated data can be handled by the conditional likelihood approach. The critical information on the start time of a left-truncated subject can be frequently obtained from human subjects. The concentration of covariate information in the observation period in a ...
In this article, we study Fisher information in left-truncated data. Two expressions of Fisher information are given in terms of distributions and hazard rates, respectively. Under Koziol-Green model, it is proved that the left-truncated data contains more Fisher information than that of the compl...

risk data of Chinese commercial banks;finally,the validation of the model is tested by stress test approach.The empirical results reveal the model not only is consistent with data characteristics but also well fits operational risk loss data;meanwhile it is robust and sensitive to loss data. ...
Hazard Plotting of Left Truncated Life Data 喜欢 0 阅读量: 28 作者: Wayne Nelson 摘要: Some life data contain groups of units that were not observed before some age. Then the number and ages of earlier failures are not known. Such data are called truncated (on the left). This paper...

Using the nonparametric estimate of the joint distribution of the truncation and censoring times and the nonparametric maximum likelihood estima.te for the sur viva1 curve we generalize the obvious method of bootstrapping to the current data. A simulation study examining the large sample behavior of...
