initialize.x {tripEstimation}R Documentation

Diagnose and initialize light level estimation.

Description

Primarily for the purposes of initializing the estimation, these functions can also be used for diagnostic purposes. position.logp both produces diagnostic images for each twilight and uses those to initialize position.

Usage

position.logp(model, x1, x2, xrest = NULL, subset = 1:model$n, initialize.x = TRUE, start = NULL, end = NULL)

initialize.x(model, x1, x2, xrest = NULL)

light.quantile(model, chain, day, seg, prob = c(0.025, 0.5, 0.975))

show.segment(model, chain, segment, day, light, k, n = 50, ...)

Arguments

model estimation model object
x1 vector of x-coordinates defining the prior grid
x2 vector of y-coordinates defining the prior grid
xrest value for remaining parameters - default is light attenuation
subset evaluate subset of segments - default uses all
initialize.x logical - create initial points for x?
chain chain object from estimation
day POSIXct vector of date-times
seg desired segment
prob probability level for quantile
start known position of release
end known position of recapture
segment vector of segment data
light vector of light data
k desired segment to show
n length of vector to evaluate
... additional arguments to be passed to plot

Details

The primary function here is position.logp, for initializing the estimation for solar.model and metropolis0.
