Re: Implementation of the OMEGA covariance matrix
Dear Ana,
I think the matrix presented in your email is already able to realize your idea
if you change '$OMEGA' to '$OMEGA BLOCK(6)'.A value of 0 in OMEGA matrix is
considered as it's fixed to this value.
Personall speaking, I suggest you take Elke/Rudy's advice, putting these three
in an $OMEGA BLOCK(3) and list the remaining OMEGAs separately in$OMEGA.
But technically, they are all the same, because the default assumption in
$OMEGA is that they are diagonal matrices with all off-diagonal elements
assumed to be 0.
Best regards,Rong

Subject: [NMusers] Implementation of the OMEGA covariance matrix
Dear NMusers,
I wonder if someone could help me to implement the OMEGA covariance matrix
below.
$OMEGA
0.09 ; PPV_VMAX
0.00 0.09 ; PPV_V1
0.00 0.00 0.09 ; PPV_V2
0.00 0.00 0.00 0.09 ; PPV_KD
0.00 0.01 0.00 0.00 0.09 ; PPV_BMAX
0.00 0.01 0.00 0.00 0.01 0.09 ; PPV KM
I don't want to fix any value to zero, but I don't know how to better
illustrate that I would like to consider a covariance between:
. V1 and Bmax
. Bmax and Km
. V1 and Km
Any advice is highly appreciated. Thank you in advance.
Kind regards,
Ana
