VCA (version 1.5.1)

getCI: Extract Confidence Intervals from VCA-Objects.

Description

This utility function acutally calls function 'VCAinference' first and then extracts the requested confidence interval (CI) information from the resulting object. You can specify single variance components (VC) or multiple. Not specifying any specific VC will return all.

Usage

getCI(
  obj,
  vc = NULL,
  type = c("vc", "sd", "cv"),
  tail = c("one-sided", "two-sided"),
  conf.level = 0.95,
  quiet = FALSE
)

Arguments

obj

(object) of class "VCA"

vc

(integer, character) specifying which variance component to extract CI for

type

(character) on which scale should results be returned

tail

(character) should one- or two-sided CI be returned

conf.level

(numeric) confidence-level to be used

quiet

(logical) TRUE = suppress additional information to be printed

Examples

data(dataEP05A2_3)
fit <- remlVCA(y~day/run, dataEP05A2_3)
getCI(fit)				# will return one-sided CI for all VC
getCI(fit, type="cv")	# now on CV-scale
getCI(fit, type="cv", conf.level=.9)
# multiple row at once
getCI(fit, vc=1:3, type="cv")
getCI(fit, vc=c("total", "error"), type="cv")
