Statistics
Calculates statistics such as the minimum, maximum, and average of a number variable. For example, a statistic on a temperature sensor reading gives the highest, lowest, and average temperature directly. Statistics and their target variable are registered in Settings > Statistics.
Note
This is streaming statistics: the values (mean, variance, and so on) are updated in real time for continuously
arriving data without keeping the whole data set in memory.
