Description Usage Arguments Details Value References
Identification of outlier data values on individual homogeneous segments using Chebyshev inequality.
The function is called by KRDetect.outliers.changepoint
and is not intended for use by regular users of the package.
1 | chebyshev.inequality.detect(x, cp.segment, L.default)
|
x |
a numeric vector of data. |
cp.segment |
an integer membership vector for individual segments. |
L.default |
a numeric value of L parameter determining the criterion for outlier detection:
the limits for outlier observations on individual segments are set as +/- L * sample standard deviation of data on the corresponding segment

This function detects outlier observations on individual segments using Chebyshev inequality. The function is exported for developer use only. It does not perform any checks on inputs since it is only convenience function for identification of outlier residuals.
A list is returned with elements:
L |
a numeric vector of L parameters used for outlier identification on individual segments |
outlier |
a logical vector specifing the identified outliers, |
