What does the Kaplan-Meier estimator aim to estimate?
What does the Kaplan-Meier estimator aim to estimate?
- Mean survival time
- Hazard function, h(t)
- Median survival time
- Survival function, S(t) (correct)
What does 'non-parametric' imply about the Kaplan-Meier estimator?
What does 'non-parametric' imply about the Kaplan-Meier estimator?
- It only works for normally distributed data
- It does not make any assumptions about the distribution of survival times (correct)
- It requires parametric input for estimation
- It assumes a specific distribution for survival times
What is the formula for the Kaplan-Meier estimator of the survival function?
What is the formula for the Kaplan-Meier estimator of the survival function?
- $ ilde{S}(t) = 1 - \frac{d}{n}$
- $ ilde{S}(t) = ilde{S}(t-1) imes (1 - \frac{d}{n})$ (correct)
- $ ilde{S}(t) = 1 - \frac{d}{N}$
- $ ilde{S}(t) = ilde{S}(t-1) imes (1 - \frac{d}{N})$
