n |
Number of random multivariate draws. |
covmat |
The covariance matrix with which to obtain correlations. |
rfunc |
Function that returns a vector of random
draws from a particular distribution. The first argument
of |
method |
The method for taking the matrix
square-root. Currently only |
... |
Further arguments to pass to |
The number, m
, of variables generated per each of
the n
observations is equal to the number of rows
(or columns) of covmat
. rfunc
is used to
fill an n
by m
matrix of uncorrelated
observations. This matrix is multiplied by the matrix
square-root (msr
) to obtain a matrix of
m
correlated random variables.
A matrix with rows giving observations and columns giving correlated variables.
