This is what the Kaplan–Meier estimator accomplishes.

In 2000, he was training to be an estimator for a commercial painting company.

Without loss of generality, assume that s 2 is the treatment group, and t 2 is the after period, then D_{22}1 and D_{11}D_{12}D_{21}0, giving the DID estimator.

The DID method can be implemented according to the table below, where the lower right cell is the DID estimator.

As opposed to the naive estimator, this estimator can be seen to use the available information more effectively: In the special case mentioned beforehand, when there are many early events recorded, the estimator will multiply many terms with a value below one and will thus take into account that the survival probability cannot be large.

Model selection techniques can be considered as estimators of some physical quantity, such as the probability of the model producing the given data.

In other fields, Kaplan–Meier estimators may be used to measure the length of time people remain unemployed after a job loss, the time-to-failure of machine parts, or how long fleshy fruits remain on plants before they are removed by frugivores.

A plot of the Kaplan–Meier estimator is a series of declining horizontal steps which, with a large enough sample size, approaches the true survival function for that population.

The Kaplan–Meier estimator can be seen as a "plug-in estimator" where each q(s).

is estimated based on the data and the estimator of S(t).

To generate a Kaplan–Meier estimator, at least two pieces of data are required for each patient (or each subject): the status at last observation (event occurrence or right-censored), and the time to event (or time to censoring).

However, this information is ignored by this naive estimator.

Note that the naive estimator cannot be improved when censoring does not take place; so whether an improvement is possible critically hinges upon whether censoring is in place.

Cities and towns in Ramanathapuram district The Kaplan–Meier estimator, also known as the product limit estimator, is a non-parametric statistic used to estimate the survival function from lifetime data.
