Description

An object which represents the information required for comparison calculated from either the control, or recovered items.

Objects from the Class

Objects can be created by calls of the form new("compitem", ...). Using two.level.comparison.items is recommended.

Slots

item.means:

a vector of the means for the observations of the item - object of class "numeric"

n.replicates:

count of the number of replicated observations of the item - object of class "numeric"

n.vars:

count of the number of propoerties observed for the item - object of class "numeric"

multivariate:

flag indicating whether the observations are multivariate - object of class "logical"

observed:

the raw observations for the item - object of class "matrix"

warn.type:

whether any warnings were issued "character"

Methods

two.level.density.LR

signature(control = "compitem", recovered = "compitem", background = "compcovar"): ...

Note

Best not to create these directly, use two.level.comparison.items instead.
