NAME

Statistics::Swoop - getting basic stats of a list in one fell swoop

SYNOPSIS

            

              
              
use Statistics::Swoop;
my @list = (qw/1 2 3 4 5 6 7 8 9 10/);
my $ss = Statistics::Swoop->new(\@list);
print $ss->max;   # 10
print $ss->min;   # 1
print $ss->sum;   # 55
print $ss->avg;   # 5.5
print $ss->range; # 9
            
          

DESCRIPTION

Usually, If we calculate some stats from list, we want maximum/minimum/sum/average/range. So Statistics::Swoop calculates them at only one loop.

METHODS

new($list)

constractor

max, maximum

getting the maximum value in $list

min, minimum

getting the minimum value in $list

range

getting the range value in $list

sum

getting the sum in $list

avg, average

getting the average in $list

count

getting the count of element

Statistics::Swoop vs Statistics::Lite

            

              
              
$ perl demos/benchmark.pl
Benchmark: running Lite, Swoop for at least 1 CPU seconds...
      Lite:  1 wallclock secs ( 1.09 usr +  0.00 sys =  1.09 CPU) @ 110.09/s (n=120)
     Swoop:  1 wallclock secs ( 1.07 usr +  0.00 sys =  1.07 CPU) @ 313.08/s (n=335)
       Rate  Lite Swoop
Lite  110/s    --  -65%
Swoop 313/s  184%    --
            
          

Statistics::Swoop is 170-190% faster than Statistics::Lite. Actually, when you calculate very small list, then Statistics::Lite is bit faster than Statistics::Swoop.
