rvvar {rv} | R Documentation |
Computes variances of the simulations of components of a random vector of array.
rvvar(x, ...)
x |
an object |
... |
further arguments passed to var |
rvvar
computes the means of the simulations
of all individual components of a random vector (rv) object.
That is, rvvar
applies the function var
to
the vector of simulations of each component of x
,
thus computing "columnwise" variances of the
matrix of simulations of x
.
A numeric vector or array (of the same dimension as that of x
)
