def concordance_index_censored(event_indicator, event_time, estimate, tied_tol=1e-8):
"""Concordance index for right-censored data
The concordance index is defined as the proportion of all comparable pairs
in which the predictions and outcomes are concordant.
Samples are comparable if for at least one of them an event occurred.
If the estimated risk is larger for the sample with a higher time of
event/censoring, the predictions of that pair are said to be concordant.
If an event occurred for one sample and the other is known to be
event-free at least until the time of event of the first, the second
sample is assumed to *outlive* the first.
When predicted risks are identical for a pair, 0.5 rather than 1 is added
to the count of concordant pairs.
A pair is not comparable if an event occurred for both of them at the same
time or an event occurred for one of them but the time of censoring is
smaller than the time of event of the first one.
Parameters
----------
event_indicator : array-like, shape = (n_samples,)
Boolean array denotes whether an event occurred
event_time : array-like, shape = (n_samples,)

estimate : array-like, shape = (n_samples,)

Concordance index for right-censored data
The concordance index is defined as the proportion of all comparable pairs
in which the predictions and outcomes are concordant.
Samples are comparable if for at least one of them an event occurred.
If the estimated risk is larger for the sample with a higher time of
event/censoring, the predictions of that pair are said to be concordant.
If an event occurred for one sample and the other is known to be
event-free at least until the time of event of the first, the second
sample is assumed to *outlive* the first.
When predicted risks are identical for a pair, 0.5 rather than 1 is added
to the count of concordant pairs.
A pair is not comparable if an event occurred for both of them at the same
time or an event occurred for one of them but the time of censoring is
smaller than the time of event of the first one.
Parameters
----------
event_indicator : array-like, shape = (n_samples,)
Boolean array denotes whether an event occurred
event_time : array-like, shape = (n_samples,)
Array containing the time of an event or time of censoring
estimate : array-like, shape = (n_samples,)

tied_tol : float, optional, default: 1e-8
The tolerance value for considering ties.
If the absolute difference between risk scores is smaller

def concordance_index_ipcw(survival_train, survival_test, estimate, tau=None, tied_tol=1e-8):
"""Concordance index for right-censored data based on inverse probability of censoring weights.
This is an alternative to the estimator in :func:`concordance_index_censored`
that does not depend on the distribution of censoring times in the test data.
Therefore, the estimate is unbiased and consistent for a population concordance
measure that is free of censoring.
It is based on inverse probability of censoring weights, thus requires
access to survival times from the training data to estimate the censoring
distribution. Note that this requires that survival times `survival_test`
lie within the range of survival times `survival_train`. This can be
achieved by specifying the truncation time `tau`.
The resulting `cindex` tells how well the given prediction model works in
predicting events that occur in the time range from 0 to `tau`.
The estimator uses the Kaplan-Meier estimator to estimate the
censoring survivor function. Therefore, it is restricted to
situations where the random censoring assumption holds and
censoring is independent of the features.
Parameters

A structured array containing the binary event indicator
as first field, and time of event or time of censoring as
second field.
estimate : array-like, shape = (n_samples,)
Estimated risk of experiencing an event of test data.
tau : float, optional
Truncation time. The survival function for the underlying
censoring time distribution :math:`D` needs to be positive
at `tau`, i.e., `tau` should be chosen such that the
probability of being censored after time `tau` is non-zero:
:math:`P(D > \\tau) > 0`. If `None`, no truncation is performed.
tied_tol : float, optional, default: 1e-8
The tolerance value for considering ties.
If the absolute difference between risk scores is smaller

Returns
-------

Concordance index for right-censored data based on inverse probability of censoring weights.
This is an alternative to the estimator in :func:`concordance_index_censored`
that does not depend on the distribution of censoring times in the test data.
Therefore, the estimate is unbiased and consistent for a population concordance
measure that is free of censoring.
It is based on inverse probability of censoring weights, thus requires
access to survival times from the training data to estimate the censoring
distribution. Note that this requires that survival times `survival_test`
lie within the range of survival times `survival_train`. This can be
achieved by specifying the truncation time `tau`.
The resulting `cindex` tells how well the given prediction model works in
predicting events that occur in the time range from 0 to `tau`.
The estimator uses the Kaplan-Meier estimator to estimate the
censoring survivor function. Therefore, it is restricted to
situations where the random censoring assumption holds and
censoring is independent of the features.
Parameters
----------
survival_train : structured array, shape = (n_train_samples,)
Survival times for training data to estimate the censoring
distribution from.
A structured array containing the binary event indicator
as first field, and time of event or time of censoring as
second field.
survival_test : structured array, shape = (n_samples,)
Survival times of test data.
A structured array containing the binary event indicator
as first field, and time of event or time of censoring as
second field.
estimate : array-like, shape = (n_samples,)
Estimated risk of experiencing an event of test data.
tau : float, optional
Truncation time. The survival function for the underlying
censoring time distribution :math:`D` needs to be positive
at `tau`, i.e., `tau` should be chosen such that the
probability of being censored after time `tau` is non-zero:
:math:`P(D > \\tau) > 0`. If `None`, no truncation is performed.
tied_tol : float, optional, default: 1e-8
The tolerance value for considering ties.
If the absolute difference between risk scores is smaller
or equal than `tied_tol`, risk scores are considered tied.
Returns
-------
cindex : float
Concordance index
concordant : int
Number of concordant pairs
discordant : int
Number of discordant pairs
tied_risk : int
Number of pairs having tied estimated risks
tied_time : int
Number of comparable pairs sharing the same time

Determine transformation parameters from data in X.
Subsequent calls to `transform(Y)` compute the pairwise
distance to `X`.
Parameters of the clinical kernel are only updated
if `fit_once` is `False`, otherwise you have to
explicitly call `prepare()` once.
Parameters
----------
X: pandas.DataFrame, shape = (n_samples, n_features)
Data to estimate parameters from.
y : None
Argument is ignored (included for compatibility reasons).
kwargs : dict
Argument is ignored (included for compatibility reasons).
Returns
-------
self : object
Returns the instance itself.

Fit the gradient boosting model.
Parameters
----------
X : array-like, shape = (n_samples, n_features)
Data matrix
y : structured array, shape = (n_samples,)
A structured array containing the binary event indicator
as first field, and time of event or time of censoring as
second field.
sample_weight : array-like, shape = (n_samples,), optional
Weights given to each sample. If omitted, all samples have weight 1.
monitor : callable, optional
The monitor is called after each iteration with the current
iteration, a reference to the estimator and the local variables of
``_fit_stages`` as keyword arguments ``callable(i, self,
locals())``. If the callable returns ``True`` the fitting procedure
is stopped. The monitor can be used for various things such as
computing held-out estimates, early stopping, model introspect, and
snapshoting.
Returns

self : object
Returns self.

Load and return the AIDS Clinical Trial dataset
The dataset has 1,151 samples and 11 features.
The dataset has 2 endpoints:
1. AIDS defining event, which occurred for 96 patients (8.3%)
2. Death, which occurred for 26 patients (2.3%)
Parameters
----------
endpoint : aids|death
The endpoint
Returns
-------
x : pandas.DataFrame
The measurements for each patient.
y : structured array with 2 fields
*censor*: boolean indicating whether the endpoint has been reached
or the event time is right censored.
*time*: total length of follow-up
If ``endpoint`` is death, the fields are named *censor_d* and *time_d*.
