var–methods {MAINT.Data}

Methods for function var in Package ‘MAINT.Data’

Description

S4 methods for function var. These methods extract estimates of variance-covariance matrices for the models fitted to Interval Data.

Usage

## S4 method for signature 'IdtNDE'
var(x)
## S4 method for signature 'IdtSNDE'
var(x)
## S4 method for signature 'IdtNandSNDE'
var(x)
## S4 method for signature 'IdtMxNDE'
var(x)
## S4 method for signature 'IdtMxSNDE'
var(x)

Arguments

x

An object representing a model fitted to interval data.

Value

For the IdtNDE, IdtSNDE and IdtNandSNDE methods or IdtMxNDE, IdtMxSNDE methods with slot “Hmcdt” equal to TRUE: a matrix with the estimated covariances.
For the IdtMxNDE, and IdtMxSNDE methods with slot “Hmcdt” equal to FALSE: a three-dimensional array with a matrix with the estimated covariances for each group at each level of the third dimension.
