Method: 

Environment: 
STATISTICA
Visual Basic (SVB) 
Function: 
Generates a random sample
drawn from an inverse Wishart distribution with dimension
p, df degrees of freedom and
covariance matrix . 
Input arguments: 
df
� The degrees of freedom for the inverse Wishart distribution from which
the random sample is drawn. 
� The covariance matrix of multivariate
normal variables. 
seed
� An optional argument for the seed for the random number generator. Given
a constant seed, repeated calls to the function will generate identical
samples. If not supplied, the STATISTICA
system random number seed and sequence will be applied. Thus, the random
number generator can be seeded programmatically from within STATISTICA
Visual Basic (SVB), for example, to create a replicable sequence of random
draws (call the SVB function Randomize([ByVal
Seed] before generating sequences of random draws using the MatrixDrawInverseWishart function without
the optional seed argument) 
Output: 
Returns a matrix storing
a random sample drawn
from an inverse Wishart sample 
Usage: 
This function draws a random
sample from an inverse Wishart distribution with . The
returned sample can also be converted to a random sample S,
with , drawn from a Wishart distribution via the relation .
