dev4mn: Computes the deviance for a sample of multinormal vector
Description
From the n observed values of a vector of size p (Y),
their expectations (EY) and the variance matrix (VY) supposed
identical for all vectors, returns the deviance, i.e.
-2*log(p(Y)).
Usage
dev4mn(Y, EY, VY)
Value
A scalar
Arguments
Y
Matrix nxp of the n observed values of length
p.
EY
Expectation of Y (matrix nxp or vector
p).
VY
Matrix of the variance of each row of Y (matrix
pxp).
Details
When EY is a vector with length ncol(Y) this supposes
that all observations have the same expectation.
