update_refined_path: Update a given section of the refined path.

In a-parton/CTStepTurn: Fitting the continuous-time step-and-turn movement model

Description

update_refined_path returns a MH update of a given section of the refined path.

Usage

update_refined_path(fixed_constant, type, fixed_values, curr_values,
  move_params, behav_params, obs)

Arguments

fixed_constant	List with components: num_states Numeric, the number of behavioural states. indep_step Boolean, True if independent step model, False if correlated. obs_error Boolean, True if observation error is to be included (independent or correlated). corr_obs_error Boolean, True if the observation error is correlated rather than independent. q.bearings Vector, index positions in move_params corresponding to bearing parameters. q.speed_mean Vector, index positions in move_params corresponding to mean speed parameters. q.speed_corr Vector, index positions in move_params corresponding to speed correlation parameters (only if correlated step model). q.speed_var Vector, index positions in move_params corresponding to speed variance parameters. q.obs_error Vector, index positions in move_params corresponding to error parameters. ideal_refined_time_diff Numeric, ideal time scale for the refined path (only if multistate case).
type	Character, the type of section being updated (start, middle, or end) from within the full path.
fixed_values	List with components set by set_fixed_values.
curr_values	List with componenets set by set_current_values.
move_params	Vector, movement parameters.
behav_params	List with components: lambda Vector, switching rates. q Square matrix (diagonal NA), switching probabilities.
obs	List with components: x Vector, observed x locations. y Vector, observed y locations. times Vector, observation times. time_diffs Vector, differences in observation times. index_on_refined_path Vector, index positions on refined path of observation times. errors List with components: x Vector, errors in x direction. y Vector, errors in y direction.

Value

List with the components:

accept

Boolean, True if proposal is accepted.

behav_fail

Boolean, True if proposal failed because of the rejection step in the behavioural proposal.

bearings

Vector of bearings.

steps

Vector of steps.

times

Vector of times (only in multi-behaviour).

behavs

Vector of behaviours (only in multi-behaviour).
