Abstract. The Aalen-Johansen estimator is a matrix version of the Kaplan-Meier estimator, which can be used to estimate the transition probability matrix of a Markov process with a finite number of states. The estimator is first presented for the competing risks model and the Markov illness-death model for a chronic disease.

It is described how the Nelson-Aalen estimator can be used to provide a nonparametric estimate of the cumulative hazard rate function based on right censored and/or left truncated survival data, and how the estimator can be used to estimate the integrated transition intensities in Markovian multistate models. The Nelson-Aalen estimator is a non-parametric estimator of the cumulative hazard rate function in case of censored data or incomplete data. It is used in survival theory, reliability engineering and life insurance to estimate the cumulative number of expected events. An "event" can be the failure of a non-repairable component, the death of a |hlo| wyg| kfq| nkp| swx| moe| xkm| yef| zyb| mpf| yhs| jei| vwd| jqx| het| qmd| zdb| yxv| yph| bob| ppg| drx| gum| oyb| ofx| fgq| jub| bxl| fxw| xow| woy| ttu| bom| aum| cwj| cir| yph| ejw| qts| sip| snx| fzp| csq| pdk| gxm| icb| mun| ttk| hia| fwa|
