GetHist: Computes PDF of observed detections for each (x,y) cell...

In r-glennie/moveds: Fit Distance Sampling Models with Animal Movement

Description

Computes PDF of observed detections for each (x,y) cell around the observer.

Usage

GetHist(working_parameter, range, transdat, auxiliary_data, delta,
  num_cells, T, ymax, buffer, fixed_sd = 0, hzfn = 1L,
  move_method = 1L)

Arguments

working_parameter	unconstrained version of parameter vector containing (detection shape, detection scale, diffusion sd)
range	to compute out to in x and y directions
transdat	matrix with (stripsize(1), numcells in y, totaltimestep, number of observations)
auxiliary_data	vector containing (area x extent, area y extent, strip width, transect_type)
delta	vector of (dx, dt) spacetime increments
num_cells	number of cells in (total space, x-direction, y-direction)
T	total time of survey for longest transect
ymax	maximum length of a transect
buffer	buffer distance
fixed_sd	if move_method = 2
hzfn	hazard function code (see ?hazardfns)
move_method	0 = 2d CDS model, 1 = 2d MDS model (movement estimated), 2 = 2d MDS model (movement fixed)

Value

matrix where (i,j) entry is cell i*dx perpendicular and j*dx forward of observer unpack auxiliary data
