variance: Construct variance

Description

A generic function to construct the different variance components of an object. You may want to use this in conjunction with bootstrap.

Usage

variance(.object, ...)
"variance"(.object, ...)
"variance"(.object, ...)
"variance"(.object, ...)
"variance"(.object, ...)
"weights"(object, c = 1, ...)

Arguments

.object, object

an object

...

arguments passed to method

c

(numeric) scalar

Examples

data("grapes", package = "sae")
data("grapesprox", package = "sae")

fitRFH <- rfh(
  grapehect ~ area + workdays - 1,
  data = grapes,
  samplingVar = "var"
)

# The variance component of a mixed linear model:
matV <- variance(fitRFH)
# The full variance matrix:
matV$V()

# The sampling error component
matV$Ve()

# the random effects component
matV$Vu()
