Web10 ott 2016 · Purpose of this answer. This answer is going to explore exact inference for normal distribution. It will have a theoretical flavour, but there is no proof of likelihood principle; only results are given. Based on these results, we write our own R function for exact inference, which can be compared with MASS::fitdistr. http://www.quantstart.com/articles/hidden-markov-models-for-regime-detection-using-r/ sweatproof sunscreen uva and uvb

WebNaïvely I'd say that you can model such a problem as a standard HMM with only one observation. If each obvervation Yti is element R, just make each multi-observation Yt an element in R^3. This will lead to n^3 possible multi-observations, if n is the number of possible single observations.
