-# Statistics package that is used in gran-extr, RTS2gran and friends.
-# Most of the routines assume a list of integers as input.
-# This package contains:
-#  - corr
-#  - mean_std_dev
-#  - cov
-#  - list_sum
-#  - list_max
-#  - list_min

-# Compute correlation of 2 vectors, having their sums precomputed.
-# Usage:  do corr(($n, $sum_1, @rest);
-#
-# Input: $n   ... number of all elements in @list_1 as well as in @list_2
-#                 (i.e. $n = $#list_1+1 = $#list_2+1).
-#        $sum_1 ... sum of all elements in @list_1
-#        @list_1 ... list of integers; first vector
-#        $sum_2 ... sum of all elements in @list_2
-#        @list_2 ... list of integers; first vector
-# Output: correlation of @list_1 and @list_2
