dsdive.tx.params: Compute transition parameters for a given depth bin

In jmhewitt/dsdive: Discrete Space Models for Dive Trajectories of Animals

Description

Computes elements of a transition matrix when given model parameters and time/space locations for a dive model that has 3 stages, descent, bottom/foraging, and ascent.

Usage

dsdive.tx.params(depth.bins, d0, s0, beta, lambda)

Arguments

depth.bins	n x 2 Matrix that defines the depth bins. The first column defines the depth at the center of each depth bin, and the second column defines the half-width of each bin.
d0	index of depth bin for which to compute transition parameters
s0	stage for which to compute parameters
beta	vector with directional preference parameters for descent and ascent stages.
lambda	vector with dive rate parameters for the descent, bottom, and ascent stages.

Examples

data('dive.sim')
attach(dive.sim)
attach(params)

dsdive.tx.params(depth.bins = depth.bins, d0 = 3, s0 = 1, 
                 beta = beta, lambda = lambda)

detach(params)
detach(dive.sim)
