Fsdb::Filter::dbcolmovingstats - compute moving statistics over a window of a column of data River stage zero No dependents

Compute moving statistics over a COLUMN of data. Records containing non-numeric data are considered null do not contribute to the stats (optionally they are treated as zeros with "-a"). Currently we compute mean and sample standard deviation. (Note w...
