What are the best practices when using Hidden Markov Models for movement data in terms of daily GPS fix frequency? Are there any? I've seen data being used in the Vignettes of moveHMM R package, for example, which use many daily, and few daily GPS fixes.
Although I know more would be better to draw accurate inferences, does anyone have an idea of what the minimum would be for daily GPS fixes in which HMM could still accurately account for behavioral state changes?
