knn {OutliersLearn}

knn

Description

This function implements the knn algorithm for outlier detection

Usage

knn(data, d, K, tutorialMode)

Arguments

data

Input Data (must be a data.frame)

d

Degree of outlier or distance at which an event is considered an outlier

K

Nearest neighbor for which an event must have a degree of outlier to be considered an outlier

tutorialMode

if TRUE the tutorial mode is activated (the algorithm will include an explanation detailing the theory behind the outlier detection algorithm and a step by step explanation of how is the data processed to obtain the outliers following the theory mentioned earlier)

Value

None, does not return any value

Examples

inputData = t(matrix(c(3,2,3.5,12,4.7,4.1,5.2,
4.9,7.1,6.1,6.2,5.2,14,5.3),2,7,dimnames=list(c("r","d"))))
inputData = data.frame(inputData)
knn(inputData,3,2,FALSE) #Can be changed to TRUE
