residuals.mpmm: residuals

In ianjonsen/mpmm: (Animal) Movement Persistence Mixed-Effects Models

residuals

Description

Extract one-step-ahead residuals

Usage

## S3 method for class 'mpmm'
residuals(
  object,
  method = "oneStepGaussianOffMode",
  trace = FALSE,
  parallel = TRUE,
  ncores = detectCores() - 1,
  ...
)

Arguments

object	an mpmm fit object
method	character naming the method to calculate one-step-ahead residuals
trace	logical; print progress to console
parallel	logical; compute in parallel
ncores	integer; number of cores to use (default = total cores detected - 1)
...	additional arguments to be ignored

Details

Wrapper function for modified oneStepPredict that calculates one-step-ahead residuals, which are residuals that account for temporal correlation in latent states. The modification allows easier parallel computation.

Value

a list with components

res	a tibble with one-step-ahead residuals for longitude and latitude
