Nonparametric Estimation of Lifetime and Disease Onset Distributions from Incomplete Observations

Abstract: In this paper we derive and investigate nonparametric estimators of the distributions of lifetime and time until onset associated with an irreversible disease that is detectable only at death. The nonparametric maximum likelihood solution requires an iterative algorithm. An alternative though closely related pair of estimators for the lifetime and onset distributions exists in closed form. These estimators are the familiar Kaplan-Meier estimator and an isotonic regression estimator, respectively. First-order a… Show more

“…The cumulative effect of unfavorable genotypes identified in the single SNP analysis on recurrence and OS, was estimated by Cox model (Flynn, 2012). Kaplan-Meier curve and log-rank test were used to assess the differences in survival and time to recurrence between patients with different genotypes (Dinse and Lagakos, 1982). All P-values in this study were two-sided, and p<0.05 was considered to be significant.…”

“…Patient survival and LFS from the time of remission were computed by the product-limit method of Kaplan and Meier. 22 Survival curves for univariate analysis of each potential predictor were compared using the log-rank test. Prognostic factors for LFS and overall survival were evaluated by multivariate analysis using Cox's proportional-hazard regression analysis.…”

“…Therefore, survival time was calculated from the date of surgery until the last date of contact or death. Univariate analysis of survival data was performed according to Kaplan and Meier (22). The log-rank test was used to test the significance between the groups.…”
