Hi, im using the n4sid algorithm and my problem is that I get different results when I use a vector to set the order:

S=n4sid(Data,1:8)

than when i directly choose the order:

S=n4sid(Data,4)

Why does this happen? When using the vector I get "better" results.

My problem is that I am using it like this:

for order=1:4
S=n4sid(Data,order)
end

and still want to get the "better" results that I get when using the vector.
