NAME

       Bio::Tools::RandomDistFunctions - A set of routines useful for generating random data in
       different distributions

SYNOPSIS

         use Bio::Tools::RandomDistFunctions;
         my $dist = Bio::Tools::RandomDistFunctions->new();
         for my $v ( 1..1000 ) {
           my $birth_dist = $dist->rand_birth_distribution($lambda);
           # ... do something with the variable
         }

DESCRIPTION

       Most of the code is based on the C implementation of these routines in Mike Sanderson's
       r8s's package.  See http://loco.biosci.arizona.edu/r8s/ for information on his software.

FEEDBACK

   Mailing Lists
       User feedback is an integral part of the evolution of this and other Bioperl modules. Send
       your comments and suggestions preferably to the Bioperl mailing list.  Your participation
       is much appreciated.

   Support
       Please direct usage questions or support issues to the mailing list:

       bioperl-l@bioperl.org

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their
       resolution. Bug reports can be submitted via the web:

APPENDIX

       The rest of the documentation details each of the object methods.  Internal methods are
       usually preceded with a _

   birth_distribution
        Title   : rand_birth_distribution
        Usage   : my $randvar = $dist->
                   rand_birth_distribution($lambda);
        Function: Returns a random number from a birth process waiting
                  time with a fixed interval
                  1.0.  Times are measured from 0=present,1=root;
        Returns : floating point number
        Args    : $lambda ( > 0 )
        References : This is based on code by Mike Sanders in r8s.

   rand_geometric_distribution
        Title   : rand_geometric_distribution
        Usage   : my $randvar = $dist->rand_geometric_distribution($param);
        Function: Returns a random geometric variate distributed with
                  parameter $param, according to
                  c.d.f. 1 - ( 1- param) ^ n
        Returns : integer
        Args    : $param ( 0 > $param < 1 )

   rand_exponentional_distribution
        Title   : rand_exponentional_distribution
        Usage   : my $var = $dist->rand_exponentional_distribution($param);
        Function: Returns a random exponential variate distributed with parameter
                  $param, according to c.d.f 1 - e^(-param * x)
        Returns : floating point number
        Args    : $param ( > 0 )

   rand_normal_distribution
        Title   : rand_normal_distribution
        Usage   : my $var = $dist->rand_normal_distribution()
        Function: Returns a random normal (gaussian) variate distributed
        Returns : floating point number
        Args    : none
