WCFPOF: WCFPOF algorithm

Description

Algorithm proposed by: Jiadong Ren, Qunhui Wu, Jiadong Ren, Changzhen Hu, Kunsheng Wang - An Approach for Analyzing Infrequent Software Faults Based on Outlier Detection

Usage

WCFPOF(data, minSupport = 0.3, mlen = 0, noCores = 1)

Arguments

data

data.frame or transactions from arules with input data

minSupport

minimum support for FPM

mlen

maximum length of frequent itemsets

noCores

number of cores for parallel computation

Value

model output (list) with all results including outlier scores

Examples

# NOT RUN {
library("fpmoutliers")
dataFrame <- read.csv(
     system.file("extdata", "fp-outlier-customer-data.csv", package = "fpmoutliers"))
model <- WCFPOF(dataFrame, minSupport = 0.001)
# }
