Hello,
I'm hoping to get some help on calculating an average time from a list of times (hour:minute:second).
Here's what my list looks like right now, it will grow (I can get the full date or change the formatting of this as well):

09:42:00

My old school way is a one liner. And will search for average from SAR, to get the data receive rate. But, I dont think it is practical or accurate,. Because it calculates to off peak hours. I am planning to change it. My cron runs every 30 mins. When my cron runs, and my time is 14:47pm,, it will... (1 Reply)

Statistics::Basic::Mean(3pm) User Contributed Perl Documentation Statistics::Basic::Mean(3pm)NAME
Statistics::Basic::Mean - find the mean of a list
SYNOPSIS
Invoke it this way:
my $avg = mean(1,2,3);
Or this way:
my $v1 = vector(1,2,3);
my $avg = avg($v1);
And then either query the values or print them like so:
print "The mean of $v1: $avg
";
my $mq = $avg->query;
my $m0 = 0+$avg;
Create a 20 point moving average like so:
use Statistics::Basic qw(:all nofill);
my $sth = $dbh->prepare("select col1 from data where something");
my $len = 20;
my $avg = mean()->set_size($len);
$sth->execute or die $dbh->errstr;
$sth->bind_columns( my $val ) or die $dbh->errstr;
while( $sth->fetch ) {
$avg->insert( $val );
if( defined( my $m = $avg->query ) ) {
print "Mean: $m
";
}
# This would also work:
# print "Mean: $avg
" if $avg->query_filled;
}
METHODS
new()
The constructor takes a single array ref or a single Statistics::Basic::Vector as arguments. It returns a Statistics::Basic::Mean
object.
Note: normally you'd use the mean() constructor, rather than building these by hand using "new()".
_OVB::import()
This module also inherits all the overloads and methods from Statistics::Basic::_OneVectorBase.
OVERLOADS
This object is overloaded. It tries to return an appropriate string for the calculation or the value of the computation in numeric
context.
In boolean context, this object is always true (even when empty).
