Fit of each entity per mode

Description

Computation of fit contributions.

Usage

 CPfitpartitioning(Xprep, n, m, p, A, B, C, laba, labb, labc)

Arguments

`Xprep`	Matrix (or data.frame coerced to a matrix) of order (`n` `x` `mp`) containing the matricized array (frontal slices)
`n`	Number of `A`-mode entities
`m`	Number of `B`-mode entities
`p`	Number of `C`-mode entities
`A`	Component matrix for the `A`-mode
`B`	Component matrix for the `B`-mode
`C`	Component matrix for the `C`-mode
`laba`	Optional vector of length `n` containing the labels of the `A`-mode entities
`labb`	Optional vector of length `m` containing the labels of the `B`-mode entities
`labc`	Optional vector of length `p` containing the labels of the `C`-mode entities

Value

A list including the following components:

`fitA`	Fit contribution for the `A`-mode entities
`fitB`	Fit contribution for the `B`-mode entities
`fitC`	Fit contribution for the `C`-mode entities

Examples

data(TV)
TVdata=TV[[1]]
labSCALE=TV[[2]]
labPROGRAM=TV[[3]]
labSTUDENT=TV[[4]]
# permutation of the modes so that the A-mode refers to students
TVdata <- permnew(TVdata, 16, 15, 30)
TVdata <- permnew(TVdata, 15, 30, 16)
# CP solution
TVcp <- CPfuncrep(TVdata, 30, 16, 15, 2, 1, 1, 1, 0, 1e-6, 10000)
# Fitpartitioning of the CP solution
FitCP <-  CPfitpartitioning(TVdata, 30, 16, 15, TVcp$A, TVcp$B, TVcp$C, 
 labSTUDENT, labSCALE, labPROGRAM)
# Fitpartitioning of the CP solution (when labels are not available)
FitCP <-  CPfitpartitioning(TVdata, 30, 16, 15, TVcp$A, TVcp$B, TVcp$C)
