I Introduction
1) Purpose of project
Our purpose of this project is to use the knowledge we learned in the statistics management class and understand how to use these information to analyse the data we collected and depending our data to find the relationship between 3 variables we choose for proving the hypotheses we bring up are correct or not. Statisitics is a very important concept to many
1. Abstract
This project is conducted by team 8 of Microeconomics class in KAIST. The objective is to analyze the item market of Cyworld using concepts and tools that we learned from the class. Cyworld is one of the biggest web communities and its profits are heavily dependent on the item market.
To collect data on the current status of the firm and how customers would react to the new system
Dependent variable is degrees of traffic jam. We choose the section to investigate, and used traffic statistics data in Seoul city’s highway traffic management center. We used weather data in the weather center, day of week data in calendar. Our unit of analysis is a car. Using these data, we score traffic jam; calculate average of each independent variable to standardization. In first hypothes
data and the two phone’s performance. We have intermediate variables (age, gender). We also have independent variables(application, cost the phone)and dependent variable(user’s satisfaction). So we think Hypotheses testing can help us enhance understanding of the relationship that among variables.
Type of investigation: correlational study

종속변수 모델을 배우면서 나온 대표적 모델은 data가 censored 되었을 경우와 truncated되었을 경우이다. 그리고 지금까지 다양한 모수와 준모수방법을 적용한 limited dependent variable 모형이 개발되었는데 그 중에서 준모수법을 사용한 가장 기본적인 censored sample selection model은 Tobin이 만든 모형을 기초로 한 방
