In the Inference of a SDE section og the Turing tutorials the noise added to the states are described in the noise model with the \phi parameters. Is \sigma supposed to capture observation noise? What is its true value?

[image] zenkavi: Is σ\sigma supposed to capture observation noise? Yes. [image] zenkavi: What is its true value? odedata = Array(sol1) + 0.8 * randn(size(Array(sol1))) 0.8. That one needs a lot longer of a chain to converge though.

Yes.

odedata = Array(sol1) + 0.8 * randn(size(Array(sol1)))

0.8. That one needs a lot longer of a chain to converge though.
