TargetColumns
Specifies pairs of columns for which to calculate correlations. For each column pair, 'col_name1:col_name2', the function calculates the correlation between col_name1 and col_name2. For each column range, '[col_index1:col_index2]', the function calculates the correlation between every pair of columns in the range. For example, if you specify '[1:3]', the function calculates the correlation between the pairs (1,2), (1,3), (2,3),(1,1),(3,3). The mininum value of col_index1 is 0, and col_index1 must be less than col_index2.
KeyName
Specifies the name for the Corr_Map output table column that contains the correlations, and by which the Corr_Map output table is partitioned.
GroupByColumns
[Optional] Specifies the names of the input columns that define the group for correlation calculation. Default behavior: All input columns belong to a single group, for which the function calculates correlation.
