statistics::basic::stddev
Statistics::Basic::StdDev(3pm) User Contributed Perl Documentation Statistics::Basic::StdDev(3pm)
NAME
Statistics::Basic::StdDev - find the standard deviation of a list
SYNOPSIS
Invoke it this way:
my $stddev = stddev(1,2,3);
Or this way:
my $v1 = vector(1,2,3);
my $std = stddev($v1);
And then either query the values or print them like so:
print "The stddev of $v1: $std
";
my $sq = $std->query;
my $s0 = 0+$std;
Create a 20 point "moving" stddev like so:
use Statistics::Basic qw(:all nofill);
my $sth = $dbh->prepare("select col1 from data where something");
my $len = 20;
my $std = stddev()->set_size($len);
$sth->execute or die $dbh->errstr;
$sth->bind_columns( my $val ) or die $dbh->errstr;
while( $sth->fetch ) {
$std->insert( $val );
if( defined( my $s = $std->query ) ) {
print "StdDev: $s
";
}
# This would also work:
# print "StdDev: $s
" $std->query_filled;
}
METHODS
new()
The constructor takes a list of values, a single array ref, or a single Statistics::Basic::Vector as arguments. It returns a
Statistics::Basic::StdDev object.
Note: normally you'd use the mean() constructor, rather than building these by hand using "new()".
query_mean()
Returns the Statistics::Basic::Mean object used in the standard deviation computation.
_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).
