Python deldup Examples

Example #1

    """ Calculates the entropy of the table _table_
        where res_col column = _res_col_.
    """
    s = 0 # sum
    for v in utils.deldup(table[res_col]):
        p = freq(table, res_col, v) / float(len(table[res_col]))
        s += p * math.log(p, 2)
    return -s
