likelihood: Log likelihood cost function

In skytrackr: A Sky Illuminance Location Tracker

Log likelihood cost function

Description

Main cost function used during optimization, combining both the fit of the illuminance data with the step-selection function.

Usage

likelihood(par, data, model, loc, roi, step_selection, ...)

Arguments

par	A vector of parameter values, including one for the uncertainty on the target values.
data	A nested data structure with validation data included.
model	A model to run with data and par settings.
loc	The previous modeled step location.
roi	A region of interest with valid sampling locations.
step_selection	A step selection function on the distance of a proposed move.
...	extra arguments to pass to the function

Value

The single log-likelihood cost of a proposed parameter set.
