Understanding narwhal diving behaviour using Hidden Markov Models with dependent state distributions and long range dependence
Fig 5
Histograms of response variables MD, DT and PD. The fit of Model 1 is indicated with black curves, for dependent lognormal (DL), independent lognormal (IL), dependent gamma (DG) and independent gamma (IG). The distribution of the fitted states are indicated with colours as given in the legend. State 1 corresponds to near surface, state 2 medium depths, and state 3 large depths.
