Abstract
Embodiments described herein relate to a method and apparatus for determining anomalies in a data set of performance metrics from a network. A computer-implemented method comprises obtaining a first tail of the data set; obtaining a first percentage threshold; determining a first threshold by inputting the first percentage threshold into a percent point function of a standard normal distribution; and utilising the first threshold to determine whether values in the first tail of the data set are anomalous.
Claims17
A computer-implemented method for determining anomalies in a data set of performance metrics from a network, the method comprising:
- obtaining a first tail of the data set;
- obtaining a first percentage threshold;
- determining a first threshold by inputting the first percentage threshold into a percent point function of a standard normal distribution;
- and
- utilising the first threshold to determine whether values in the first tail of the data set are anomalous.
An apparatus for determining anomalies in a data set of performance metrics from a network, the apparatus comprising processing circuitry configured to cause the apparatus to:
- obtain a first tail of the data set;
- obtain a first percentage threshold;
- determine a first threshold by inputting the first percentage threshold into a percent point function of a standard normal distribution;
- and
- utilise the first threshold to determine whether values in the first tail of the data set are anomalous.
