WebApr 14, 2024 · We used multiple imputation to replace missing values of baseline PSA. The multiple imputation model included all variables included in the analysis models (listed in Table 1) and the analysis models outcome variables (i.e., the Nelson Aalen estimates of the cumulative hazard function and censoring indicators). 26 Webfunction. Here we’ll use the Nelson-Aalen estimate of the cumulative hazard. The survival function is used to weight di erences between the observed and expected cumulative hazard. Recall that the Nelson-Aalen estimate of the cumulative hazard is He(t) = X t t i d i Y i In a one-sample problem, you test whether the hazard rate h(t) is equal ...

WebThis function is useful for imputing variables that depend on survival time. White and Royston (2009) suggested using the cumulative hazard to the survival time H0 (T) … WebThe Kaplan–Meier estimator can be used to estimate the survival function. The Nelson–Aalen estimator can be used to provide a non-parametric estimate of the cumulative hazard rate function. Computer software for survival analysis.
