Identifying Outliers

To find the number of outliers (points above a given threshold, e.g. 10.0), use the expression:

 length(delete(W1, W1 < 10.0))

To identify the mean and standard deviation of those outliers, generate the series of outliers:

 delete(W1, W1 < 10.0)

and take the MAX and STDEV of the resulting series.
