Summary Method for an ARIMA model fit

DESCRIPTION:

Returns the same ARIMA model object but prints out extended information about the model fit

USAGE:

summary.arima(object, digits=4) 

REQUIRED ARGUMENTS:

object
the fitted model of "arima" class. This is assumed to be the result of "arima.mle" fit. The components returned by the arima.mle function must be available in object.

OPTIONAL ARGUMENTS:

digits
number of decimal digits after the decimal point. The default is set to 4.

DETAILS:

This function is a method for the generic function summary for the class "arima". It can be invoked by calling summary with an object of the appropriate class. Alternatively, it can be invoked directly by calling summary.arima regardless of the class of the object.

EXAMPLES:

# Fit a Box-Jenkins (0,1,1)x(0,1,1)12 Airline model to the 
<CODE>ship</CODE> data 
# Use zeros as the starting values for the optimizer 
al.mod <- list(list(order=c(0,1,1)), list(order=c(0,1,1), period=12)) 
fit <- arima.mle(ship, model=al.mod) 
summary(fit)
