ReduceToLowLand {GeneralizedUmatrix}

ReduceToLowLand

Description

ReduceToLowLand

Usage

ReduceToLowLand(BestMatchingUnits, GeneralizedUmatrix, Data = NULL, Cls = NULL,
Key = NULL, LowLimit,Force=FALSE)

Arguments

BestMatchingUnits

[1:n,1:n,1:n] BestMatchingUnits =[BMkey, BMLineCoords, BMColCoords]

GeneralizedUmatrix

[1:l,1:c] U-Matrix heights in Matrix form

Data

[1:n,1:d] data cases in lines, variables in Columns or [] or 0

Cls

[1:n] a possible classif( ication of the data or [] or 0

Key

[1:n] the keys of the data or [] or 0

LowLimit

GeneralizedUmatrix heights up to this are considered to lie in the low lands default: LowLimit = prctile(Uheights,80) nur die 80# tiefsten

Force

==TRUE: Always perform reduction

Value

LowLandBM

the unique BestMatchingUnits in the low lands of an u-Matrix

LowLandInd

index such that UniqueBM = BestMatchingUnits(UniqueInd,]

LowLandData

Data reduced to LowLand: LowLandData = Data(LowLandInd,]

LowLandCls

Cls reduced to LowLand: LowLandCls = Cls(LowLandInd)

LowLandKey

Key reduced to LowLand: LowLandKey = Key(LowLandInd)
