and stddev
.
Multiple counts can be combined using the combineWith

the minimum value of the (non-NaN) data points
the maximum value of the data points
the sum across all data points
the sum of the squares of the differences between the data points and their mean
the number of (non-NaN) data points accounted for
the number of counts which have been combined in this count (1 for a single count). this is needed for the pooled standard deviation
