In HDtweedie: The Lasso for Tweedie's Compound Poisson Model Using an IRLS-BMD Algorithm

A motor insurance dataset

Description

The motor insurance dataset is originially retrieved from the SAS Enterprise Miner database. The included dataset is generated by re-organization and transformation as described in Qian et al. (2016).

Usage

data(auto)

Details

This data set contains 2812 policy samples with 56 predictors. See Qian et al. (2016) for a detailed description of the generation of these predictors. The response is the aggregate claim loss (in thousand dollars). The predictors are expanded from the following original variables:

CAR_TYPE:

car type, 6 categories

JOBCLASS:

job class, 8 categories

MAX_EDUC:

education level, 5 categories

KIDSDRIV:

number of children passengers

TRAVTIME:

time to travel from home to work

BLUEBOOK:

car value

NPOLICY:

number of policies

MVR_PTS:

motor vehicle record point

AGE:

driver age

HOMEKIDS:

number of children at home

YOJ:

years on job

INCOME:

income

HOME_VAL:

home value

SAMEHOME:

years in current address

CAR_USE:

whether the car is for commercial use

RED_CAR:

whether the car color is red

REVOLKED:

whether the driver's license was revoked in the past

GENDER:

gender

MARRIED:

whether married

PARENT1:

whether a single parent

AREA:

whether the driver lives in urban area

Value

A list with the following elements:

x	a [2812 x 56] matrix giving 2812 policy records with 56 predictors
y	the aggregate claim loss
