seasonal (version 1.2.1)

summary.seas: Summary of a X13-ARIMA-SEATS seasonal adjustment

Description

Like the corresponding method for "lm" objects, the method for "seas" objects returns the estimated coefficients, its standard errors, z-statistics and corresponding (two-sided) p-values. Coefficients are returned both for the exogenous regressors and the coefficients of the ARIMA model.

Usage

## S3 method for class 'seas':
summary(object, ...)
## S3 method for class 'summary.seas':
print(x, digits = max(3, getOption("digits") - 3),
  signif.stars = getOption("show.signif.stars"), ...)

Arguments

object

an object of class "seas", usually, a result of a call to seas.

x

an object of class "summary.seas", usually, a result of a call to summary.seas.

digits

the number of significant digits to use when printing.

signif.stars

logical. If TRUE, 'significance stars' are printed for each coefficient.

...

further arguments passed to or from other methods.

Value

• summary.seas returns a list containing the summary statistics included in object, and computes the following additional statistics:
• coefficients
  a named matrix containing coefficients, standard deviations, t-values and p-values
• transform
  character string with the type of intial transformation
• The print method prints the summary output in a similar way as the method for "lm".

Details

The lower part of the output shows additional information on the estimation: [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Examples

m <- seas(AirPassengers)
