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.

       This code tries to be fast and use available faster BigInt and GMP library methods when those modules are available.

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

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.
		     Ross, Stochastic Processes, p. 145 for the density

   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
