InstrumentArcCrossStatistics
Computes statistics of selected data columns between two instrument files arc wise. The outputfileStatisticsTimeSeries contains for every arc one (mid) epoch with statistics column(s). Possible statistics are
- Correlation \[ \rho = \frac{\sum_i x_i y_i}{\sqrt{(\sum_i x_i^2) (\sum_i y_i^2})}, \]
- Error RMS \[ rms = \sqrt{\frac{1}{N}\sum_i (x_i-y_i)^2}, \]
- Nash-Sutcliffe coefficient (NSC) \[ nsc = 1- \frac{\sum_i (x_i-y_i)^2}{\sum_i (y_i-\bar{y})^2}. \]
With perColumn separate statistics for each selected data column are computed, otherwise an overall value is computed.
