display: Graphs for ARMA models

Description

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

Usage

display(um, ...)
# S3 method for 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,
  ...
)
# S3 method for default
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))
