教育目標

資料視覺化分析對於清理資料、探索資料結構、偵測界外值(outliers)及異常群體、辨識趨勢及叢聚(clusters)、發現局部模式(pattern)、評估模型分析輸出(output)、與呈現分析結果,都相當有幫助。資料視覺化分析對於探索性數據分析(exploratory data analysis)、資料採礦(data mining)、網絡分析(network analysis)更是不可或缺的。 本課程主要目標為使用 R 軟體與實際調查資料,來展現資料視覺化分析能展現資料中的哪些資訊。透過實際操作來增加具體設計並畫出統計圖像、詮釋統計圖像的經驗,來有效率地了解資料視覺化分析。

課程概述

Data visualization is an important issue that can arise in high-dimensional data analysis. It has become increasingly more important due to the advent of computer and graphics technology. The difficulty lies on how to visualize a high dimensional structure or data set. Such kinds of questions do have a common root in Statistics. This course will introduce some statistical methodologies useful for exploring voluminous data. The main topics include, but not limited to, two parts. The first part is based on dimension reduction methods which include Principal Component Analysis (PCA), Projection Pursuit, Sliced Inverse Regression (SIR), Principal Hessian Direction (PHD), Minimum Average Variance Estimation (MAVE) and LASSO etc. The second part is just a collection of dimension free methods which consist of Parallel Coordinate Plot, Matrix Visualization, Generalized Association Plots (GAP) etc. Most of methods will be discussed from both theoretical and practical perspective for the entire course. Examples from various application areas will be given.
