Wiley Classics Library. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling or hypothesis testing task. GND : Adding transformed explanatory variables, for example.
Don't have an account. Goodreads is hiring. The use of 3D plots and the coding of color as an additional dimension of data, provided us novel insights into the compositional relation- ships between lipoproteins. De, K.
This text explains the necessity for and uses of both exploratory data analysis and robust and resistant methods in statistical practice. Edited by pre-eminent statisticians, it provides the conceptual, logical, and sometimes mathematical support for the more basic techniques of these methods.

In this chapter, the reader will learn about the most common tools available for exploring a dataset, which is essential in order to gain a good understanding of the features and potential issues of a dataset, as well as helping in hypothesis generation. Exploratory data analysis EDA is an essential step in any research analysis. The primary aim with exploratory analysis is to examine the data for distribution, outliers and anomalies to direct specific testing of your hypothesis. It also provides tools for hypothesis generation by visualizing and understanding the data usually through graphical representation [ 1 ]. EDA aims to assist the natural patterns recognition of the analyst. Finally, feature selection techniques often fall into EDA. Since the seminal work of Tukey in , EDA has gained a large following as the gold standard methodology to analyze a data set [ 2 , 3 ].
