I Model Specification
A casual relation among damage amount of traffic accident being occurred on the highway, factors affected to traffic accident, such as climate, time, and attribute of driver that can be identified during the process of accident investigation, damaged facility, casualties and surrounding situation will be verified using multiple linearregression analysis. Regarding damage
multiple linearregression model was used. First, 10 explanatory variables that are likely to affect selling price of the car were potentially set and the data were collected. In this course, we referred to website (http://www.enuri.com/car) that sells new cars. Next, the standard regression assumptions were checked. Finally, fitness of model was examined by deciding whether the price of the car

Research Purpose
Nowadays, there are many different models of cars and their prices range.
We want to know what the factors are which affect the selling price of the car and how much each variable explains the selling price.
Research Process
To determine if there is a correlation between various factors and the selling price of the car, the multiple linearregression model was used
