rvvar | R Documentation |
Computes variances of the simulations of components of a random vector of array.

x |

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
.
rvsd
applies the function sd
to the vector of simulations of
each component of x
, thus computing "columnwise" standard deviations
of the matrix of simulations of x
.
A numeric vector or array (of the same dimension as that of
x
)
