This approach to designing independence proposals can be extended to other models where the model of the state is linear-Gaussian see Jungbacker and Koopman, Fabrice Larribe and Paul Fearnhead. As seen above, whether this is the case will depend on the amount of dependence in the state-model. However the former method can only be applied to a limited class of models, and the latter used the linear-Gaussian nature of the state-model. Paul a 2 postes sur son profil.

Updating schemes, correlation structure, blocking and parameterization for the Gibbs sampler.
Non-centered parameterizations for hierarchical models and data augmentation. In situations where it is not possible to update the whole state process from its full conditional, one possibility is to use an independence proposal to update jointly a block of state values. We then use the current estimate of the posterior distribution in order to choose the next stimulus level.

An example of how the mixing of the MCMC algorithm is affected by the dependence within the state-model is shown in the top row of Table 1.
