sim_post: simulate from the posterior of a 'ssm' fit.

In ianjonsen/foieGras: Fit Continuous-Time State-Space and Latent Variable Models for Quality Control of Argos Satellite (and Other) Telemetry Data and for Estimating Changes in Animal Movement

simulate from the posterior of a ssm fit.

Description

simulates track locations from the joint precision matrix of a ssm model fit. Currently, the joint precision of the SSM movement parameters is not included (ie. a full posterior simulation).

Usage

sim_post(x, what = "predicted", reps = 1, sim_only = FALSE)

Arguments

x	a ssm fit object with class ssm_df
what	simulate fitted or predicted locations
reps	number of replicate tracks to simulate from the ssm model fit object
sim_only	logical, do not include ssm estimated locations in output (default is FALSE)

Value

a fG_sim_post object containing the paths simulated from a ssm fit object

Examples

fit <- fit_ssm(ellie, model = "crw", time.step = 24)
psim <- sim_post(fit, "p", reps = 10)
plot(psim, type = "lines")
