summary.FRBmultireg: Summary Method for Objects of Class 'FRBmultireg'

Description

Summary method for objects of class FRBmultireg, and print method of the summary object.

Usage

# S3 method for FRBmultireg
summary(object, confmethod = c("BCA", "basic", "both"), digits = 3, 
print.CI=FALSE, sep="", ...)
# S3 method for summary.FRBmultireg
print(x, ...)

Value

summary returns an object of class summary.FRBmultireg, which contains the following components:

responses

the names of the response variables in the fitted model

covariates

the names of the covariates (predictors) in the fitted model

Betawstd

a data frame containing the coefficient estimates and their bootstrap standard errors

Sigma

estimate for the error covariance matrix

table.bca

a list with for each response variable a matrix containing the estimates, standard errors, lower and upper limits of the BCa confidence intervals, p-values and a significance code (only present when confmethod="BCA" or confmethod="both")

table.basic

a list with for each response variable a matrix containing the estimates, standard errors, lower and upper limits of the basic bootstrap confidence intervals, p-values and a significance code (only present when confmethod="basic" or confmethod="both")

method

multivariate regression method that was used

conf

confidence level that was used

digits

number of digits for printing

Arguments

object

an R object of class FRBmultireg, typically created by FRBmultiregS, FRBmultiregMM or FRBmultiregGS

confmethod

which kind of bootstrap confidence intervals to be displayed: 'BCA'= bias corrected and accelerated method, 'basic'= basic bootstrap method, 'both'=both kinds of confidence intervals

digits

number of digits for printing (default is 3)

print.CI

logical: Should Confidence intervals be printed?

sep

Symmbol to separate columns in output. Default is ""

x

an R object of class summary.FRBmultireg, resulting for example from summary(FRBmultiregS(),...)

...

potentially more arguments to be passed to methods

Details

The print method displays in a “familiar way” the components of the summary object, which are listed in the Value section.
