nag_rand_logistic (g05slc) generates a vector of pseudorandom numbers from a logistic distribution with mean $a$ and spread $b$.
The distribution has PDF (probability density function)
nag_rand_logistic (g05slc) returns the value
where
$y$ is a pseudorandom number uniformly distributed over
$\left(0,1\right)$.
One of the initialization functions
nag_rand_init_repeatable (g05kfc) (for a repeatable sequence if computed sequentially) or
nag_rand_init_nonrepeatable (g05kgc) (for a non-repeatable sequence) must be called prior to the first call to nag_rand_logistic (g05slc).
Not applicable.
nag_rand_logistic (g05slc) is threaded by NAG for parallel execution in multithreaded implementations of the NAG Library.
Please consult the
x06 Chapter Introduction for information on how to control and interrogate the OpenMP environment used within this function. Please also consult the
Users' Note for your implementation for any additional implementation-specific information.
None.
This example prints the first five pseudorandom real numbers from a logistic distribution with mean
$1.0$ and spread
$2.0$, generated by a single call to nag_rand_logistic (g05slc), after initialization by
nag_rand_init_repeatable (g05kfc).
None.
