aggregates data by calculating the mean value |
...
This method will give the same results as the instantaneoustoMean transformation transformation while setting the includeFirstValueOfAggregationPeriodInCalculation option to false. However, before 2016.02 it has no option to ignore missing values in the input series. This has been implemented in 2016.02 build 62835.
