<div dir="ltr"><div><div><div><div><div><div>Hello all,<br><br></div>I am currently
working on a spatio-temporal model that we are hoping to implement in
ADMB. Unfortunately, I am very new at ADMB and am looking for a little
help. Specifically, I am looking to see if there are any examples of
code for a multivariate linear state-space model:<br>
<br></div>Y(t) = X(t) + e(t), e(t) \sim N(0,s2e I)<br></div>X(t) = M*X(t-1) + eta(t), eta(t) \sim N(0,Q)<br><br></div>where
Y(t) is the data vector, X(t) is the latent variable vector, M is the propagator matrix, and
s2e and Q the innovation variance and latent covariance, respectively. <br>
<br></div>There are a few examples of state-space models, but I did not
see one using a very bare bones set-up like this. Any help would be
much appreciated for a lowly beginner like me. <br><br></div>Sincerely,<br>Dan Gladish</div>
