Abstract

Chatterjee (2021) proposed a new correlation coefficient ξ. Focusing on two questions (1. Is ξ coefficient distinguishable for Anscombe's quartet data set?, 2. How does the ξ coefficient value change according to the number of data for various kinds of scatterplots?), an exploratory data analysis is attempted for ξ coefficient. We can compare three measures (ξ coefficient, Pearson's correlation coefficient and mutual information).

Chatterjee (2021)는 새로운 상관계수 ξ를 제안하였다. 두 가지 질문 (1. Anscombe's quartet 데이터셋에 대하여 ξ 계수는 구별이 가능한가?, 2. 다양한 종류의 산점도에서 데이터의 개수에 따라 ξ 계수 값의 변화는 어떠한가?)을 중심으로 ξ 계수에 대한 탐색적자료분석을 시도하였다. 세 가지 측도 (ξ 계수, 피어슨상관계수, 상호정보)를 서로 비교하였다.
