extremal.index.Kgaps {envoutliers} | R Documentation |
Estimation of an extremal index using the K-gaps estimator suggested in (Suveges and Davison, 2010).
The function is called by KRDetect.outliers.EV
and is not intended for use by regular users of the package.
extremal.index.Kgaps(x, u, K)
x |
a numeric vector of observations. |
u |
a numeric value giving threshold. |
K |
a nonnegative integer giving the value of K parameter (Suveges and Davison, 2010). |
This function computes the K-gaps estimate of extremal index suggested in (Suveges and Davison, 2010).
The function is exported for developer use only. It does not perform any checks on inputs since it is only convenience function used within KRDetect.outliers.EV
.
a numeric value of an extremal index estimate
