# arma.loop

##### Loop through a series of ARIMA models and display coordinated tables and diagnoastic graphs.

Loop through a series of ARIMA models and display coordinated tables and diagnostic graphs. The complete example from the Heiberger and Teles article, also included in the Heiberger and Holland book, is illustrated.

##### Usage

```
arma.loop(x,
model, ## S-Plus
order, seasonal, ## R
series=deparse(substitute(x)), ...)
```diag.arma.loop(z,
x=stop("The time series x is needed in S-Plus when p=q=0."),
lag.max = 36, gof.lag = lag.max)

rearrange.diag.arma.loop(z)

##### Arguments

- x
Time series vector. In S-Plus,

`x`

must be an`"rts"`

.- model
A valid S-Plus

`model`

for- order, seasonal
A valid R

`order`

and`seasonal`

for- series
Character string describing the time series.

- …
Additional arguments for

`arima.mle`

or`arima`

.- z
For

`diag.arma.loop`

, an "arma.loop" object. For`rearrange.diag.arma.loop`

, an "diag.arma.loop" object.- lag.max
Maximum lag for the acf and pacf plots.

- gof.lag
Maximum lag for the gof plots.

##### Details

S-Plus and R have different functions, with different input argument names and different components in their value.

##### Value

`arma.loop`

: `"arma.loop"`

object which is a matrix of
lists, each containing an arima model.

`diag.arma.loop`

: `"diag.arma.loop"`

object which is a
matrix of lists, each containing the standard diagnostics for one
arima model.

`rearrange.diag.arma.loop`

: List of matrices, each containing
all the values for a specific diagnostic measure collected from the
set of arima models.
