1. Introduction
Nowadays, business surroundings are getting severe-We need marketing strategy
The marketing information is very important to make a good marketing strategy
Importance of marketing research in the sports industry field
Decision Tree and its application in the sports industry

field of the decision making.
At the time when limited number of corporations were competing, just the sense or experience of CEO could lead businesses, but like now, in the competitive market, we have to have faster and more precise information to meet customer’s desire. So we need objective information collected and analyzed by scientific methods to make a successive marketing decision.
1 – 1. Decision Tree Using User-defined Algorithm(By SAS E-miner)
Splitting Condition : Entropy Reduction
Minimum Number of Observation : 46(1% of Data Set,
To avoid Overfitting & Underfitting)
Test Accuracy = 1266/1389 = 91.74%
Accuracy is increased little as Decision Tree used by C4.5
Because, Decision Tree is sufficiently good classifier.

while (u > 0) {
if (u < v) SWAP(u, v);
u = u - v;
}
return v;

Ⅰ. 개요
대부분의 유럽의 공중망사업자들이 고품질의 기간망으로서 또한 종단간 통신(end-to-end com munications)의 핵심으로서의 ATM이 지닌 가능성에 주목하고 그 평가작업에 열중하고 있다는 점이다. 현재 진행중인 현장시험이 성공적으로 판명되면 ATM은 각 지역 및 국가의 정보고속도로를 연결하는 국제
