# Exploratory Data Analysis

We were together learning how to use the analysis of variance, and perhaps it is worth while stating an impression that I have formed-that the analysis of variance, which may perhaps be called a statistical method, because that term is a very ambiguous one — is not a mathematical theorem, but rather a convenient method of arranging the arithmetic. Just as in arith-metical textbooks — if we can recall their contents — we were given rules for arranging how to find the greatest common measure, and… Expand

TESTING LINEARITY USING POWER TRANSFORMS OF REGRESSORS by Yae In

- 2015

We develop a method of testing linearity using power transforms of regressors, allowing for stationary processes and time trends. The linear model is a simplifying hypothesis that derives from the… Expand

Visual analysis of self-organizing maps

In this paper, algorithms for multivariate data projection , based on topology or distance preserving map-pings, as well as tools and techniques for projection display and user interaction are brieey… Expand

A New Challenge for Information Mining

- Geography
- 2017

In the field of "Data Exploration" many approaches have been developed to solve the problem of management of big data that are also semantically rich. Nowadays, there is a strong need to support the… Expand

Outlier Detection over Sliding Windows for Probabilistic Data Streams

- Computer Science
- Journal of Computer Science and Technology
- 2010

The problem of detecting an outlier over a set of possible world instances is equivalent to the problem of finding the k-th element in its neighborhood and a dynamic programming algorithm is proposed to reduce the detection cost from O(2|R( e; d) to O(|k·R(e; d)|), where E is the d-neighborhood of e.
