Math::Random::OO::BootUserpContributed Perl DocuMath::Random::OO::Bootstrap(3)

NAME
       Math::Random::OO::Bootstrap - Generate random numbers with bootstrap
       resampling from a non-parametric	distribution

VERSION
       version 0.22

SYNOPSIS
	 use Math::Random::OO::Bootstrap;
	 @sample = qw( 2 3 3 4 4 5 5 6 6 7 );
	 $prng = Math::Random::OO::Bootstrap->new(@sample);
	 $prng->seed(42);
	 $prng->next() # draws randomly	from the sample

DESCRIPTION
       This subclass of	Math::Random::OO generates random numbers with
       bootstrap resampling (i.e. resampling with replacement) from a given
       set of observations.  Each item in the sample array is drawn with equal
       probability.

METHODS
   "new"
	$prng =	Math::Random::OO::Bootstrap->new(@sample);
	$prng =	Math::Random::OO::Bootstrap->new(\@sample);

       "new" takes either a list or a reference	to an array containing a set
       of observations and returns a new "Math::Random::OO::Bootstrap" object.
       If a reference is provided, the object will make	an internal copy of
       the array to avoid unexpected results if	the source reference is
       modified.

       If the desired sample is	an array of array references, the list must be
       enclosed	in an anonymous	array reference	to avoid ambiguity.

	@sample	= ( [ 1, 2, 3],	[2, 3, 4] );

	# Correct way
	$prng =	Math::Random::OO::Bootstrap->new( [ @sample ] );

	# Incorrect -- will only use [1, 2, 3] as the desired sample
	$prng =	Math::Random::OO::Bootstrap->new( @sample );

       It is an	error to call "new" with no arguments.

   "seed"
	$rv = $prng->seed( @seeds );

       This method seeds the random number generator.  At the moment, only the
       first seed value	matters.  It should be a positive integer.

   "next"
	$rnd = $prng->next();

       This method returns the next random number from the random number
       generator by resampling with replacement	from the provided data.	It
       does not	take any parameters.
