Fsdb::Filter::dbcolscorrelate - find the coefficient of correlation over columns
Compute the coefficient of correlation over two (or more) columns. The output is one line of correlations. With exactly two columns, a new column *correlation* is created. With more than two columns, correlations are computed for each pairwise combin...
