randomnumbers.binomial

Generate binomially distributed random numbers

Synopsis
binomial(number, probability, shape)

Description
The binomial function will generate numbers that follow a binomial distribution. See the general tool description for a definition of the point probabilities.

The number, N, can be any positive integer and the probability must be a number between zero and one. The result will be integers in the range 0 $\leq$ x $\leq$ N. The shape can be either an integer or a vector of integers where all the values are greater than zero. The default value of one will produce a scalar output.

Arguments

number	in	Number of trials
		Allowed:	integer
		Default:	1
probability	in	probability of success for one trial
		Allowed:	double
		Default:	0.5
shape	in	Shape of the output array
		Allowed:	integer or a vector of integers
		Default:	1

Returns
An integer scalar or array.

Example

      include 'randomnumbers.g'
      rand := randomnumbers();
      print rand.binomial(2, shape=100);
      rand.done()

This example will print random numbers that correspond to tossing two coins one hundred time and counting the number of heads. Hence zero will appear one quarter of the time, one appear half of the time and two will appear one quarter of the time.
