Parameter estimates from three models fitted to a blue shark track. The Lower and Upper columns are the lower and upper bounds of 95% uncertainty intervals around the estimates. These correspond to 95% confidence intervals for the HMMM and moveHMM, and 95% credible intervals for the DCRWS${}_{\mathrm{NOME}}$. The only two parameters in common among all three models are the switching probabilities, ${\mathrm{\alpha }}_{1,1}$ and ${\mathrm{\alpha }}_{2,1}$. Because this track had some step lengths equal to zero, the two parameters ${\mathrm{\zeta }}_1$ and ${\mathrm{\zeta }}_2$ were used to estimate zero‐inflation for each behavior when using moveHMM
