Graphs for ARMA models

Description

display shows graphs characterizing one or a list of ARMA models.

Usage

display(um, ...)

## S3 method for class 'um'
display(
  um,
  lag.max = 25,
  n.freq = 501,
  log.spec = FALSE,
  lags.at = NULL,
  graphs = c("acf", "pacf", "spec"),
  byrow = FALSE,
  eq = TRUE,
  cex = 1.25,
  ...
)

## Default S3 method:
display(um, ...)

Arguments

um	an object of class um or a list of these objects.
...	additional arguments.
lag.max	number of lags for ACF/PACF.
n.freq	number of frequencies for the spectrum.
log.spec	logical. If TRUE log spectrum is computed.
lags.at	the lags of the ACF/PACF at which tick-marks are to be drawn.
graphs	vector of graphs.
byrow	orientation of the graphs.
eq	logical. If TRUE the model equation is used as title.
cex	double. Font size for equation text.

Examples

um1 <- um(ar = "(1 - 0.8B)(1 - 0.8B^12)")
um2 <- um(ma = "(1 - 0.8B)(1 - 0.8B^12)")
display(list(um1, um2))
