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.
