R Documentation

Compute and (optionally) plot residuals from SSM model fit

Description

Compute and (optionally) plot residuals from SSM model fit

Usage

checkSSMresiduals(
  y,
  w,
  show.plot = TRUE,
  resid.type = c("standardized", "unstandardized")
)

Arguments

`y`	a `paleoTS` object
`w`	a `paleoTSfit` object, where the fitting functions uses SSM
`show.plot`	logical, if `TRUE`, several diagnostic plots are shown
`resid.type`	residual type, either "standardized" or "unstandardized"

Details

It is recommended that resid.type be set to the default, "standardized", which will scale residuals by their expected standard deviation

Value

a vector of residuals, returned invisibly

Examples

y <- sim.GRW(ns = 50, ms = 0.2)
w <- fitSimple(y, model = "URW", method = "SSM")  # wrong model
checkSSMresiduals(y, w, show.plot = TRUE) # positive residuals show model mis-fit
