display {tfarima}

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,
  graphs = c("acf", "pacf", "spec"),
  byrow = FALSE,
  eq = TRUE,
  ...
)

## 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.

graphs

vector of graphs.

byrow

orientation of the graphs.

eq

logical. If TRUE the model equation is used as title.

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))
