fraudulent: Fraudulent Automobile Insurance Claims Data

Description

The fraudulent data frame has 42 rows and 12 columns. 127 claims arising from automobile accidents in 1989 in Massachusetts (USA). Each claim was classified as either fraudulent or legitimate by consensus among four independent claims adjusters who examined each case file thoroughly. An exploratory analysis by Derrig and Weisberg (1993) identified 10 binary indicators, each of which denotes the presence or absence of a potential fraud characteristic in the claim situation. They fall into three broad groups relating to Accident (AC1, AC9 and AC16), Claimant (CL7 and CL11), and Injury (IJ2, IJ3, IJ4, IJ6 and IJ12).
