Construct a parameter list for the built-in Gamma step-length and wrapped
normal turning-angle HMM used in examples and simulations.
Usage
create_hmm_movement_parameters(
initial_probs = c(0.65, 0.35),
transition_matrix = matrix(c(0.92, 0.08, 0.12, 0.88), nrow = 2, byrow = TRUE),
step_shape = c(2, 7),
step_rate = c(3, 2),
angle_mean = c(0, 0),
angle_sd = c(1.6, 0.35)
)
Arguments
- initial_probs
Numeric probability vector for the initial latent state.
- transition_matrix
Square transition probability matrix.
- step_shape, step_rate
State-dependent Gamma shape and rate parameters.
- angle_mean, angle_sd
State-dependent wrapped-normal mean and standard
deviation parameters.
Value
A list of HMM movement parameters.
