Description
This statisticsEnsemble transformation will compute the index of the ensemble time series that has the max value. Input is an ensemble with multiple time series. Output is one time series. Per time step the index of the ensemble time series with the max value is calculated for that time step and written to the output value. This transformation assumes all members are in ascending order starting at 0 in steps of 1.
