  • If you were to ask a random sampling of people what data analysis is, most would say that it is the process of calculating and summarizing data to get an answer to a question. In one sense, they are correct. However, the actions they are describing represent only a small part of the process known as data analysis

  • These days it seems like everyone is collecting data. But all of that data is just raw information -- to make that information meaningful, it has to be organized, filtered, and analyzed. Anyone can apply data analysis tools and get results, but without the right approach those results may be useless. Author Philipp Janert teaches you how to think about data: how to effectively approach data analysis problems, and how to extract all of the available information from your data.

  • n these lecture notes, a selection of frequently required statistical tools will be introduced and illustrated. They allow to post-process data that stem from, e.g., large-scale numerical simulations. From a point of view of data analysis, the concepts and techniques introduced here are of general interest and are, at best, employed by computational aid. Consequently, an exemplary implementation of the presented techniques using the Python programming language is provided.

  • We describe our investigations in generating textual summaries of physiological time series data to aid medical personnel in monitoring babies in neonatal intensive care units. Our studies suggest that summarization is a communicative task that requires data analysis techniques for determining the content of the summary. We describe a prototype system that summarizes physiological time series.

  • This book synthesizes current research in the integration of computational intelligence and pattern analysis techniques, either individually or in a hybridized manner. The purpose is to analyze biological data and enable extraction of more meaningful information and insight from it. Biological data for analysis include sequence data, secondary and tertiary structure data, and microarray data.

  • Nowadays, huge amount of multimedia data are being constantly generated in various forms from various places around the world. With ever increasing complexity and variability of multimedia data, traditional rule-based approaches where humans have to discover the domain knowledge and encode it into a set of programming rules are too costly and incompetent for analyzing the contents, and gaining the intelligence of this glut of multimedia data. The challenges in data complexity and variability have led to revolutions in machine learning techniques.

  • Methods for analysing trauma injury data with missing values, collected at a UK hospital, are reported. One measure of injury severity, the Glasgow coma score, which is known to be associated with patient death, is missing for 12% of patients in the dataset. In order to include these 12% of patients in the analysis, three different data imputation techniques are used to estimate the missing values.

  • The last quarter of the last century has witnessed major advancements that have brought imaging and radioanalytical techniques to a paramount status in life sciences and industry. Generally speaking, the scope of radiation imaging and radioanalytics covers data acquisi‐ tion, data processing, and data analysis, involving theories, methods, systems and applica‐ tions. While detection and post-processing techniques become increasingly sophisticated, traditional and emerging modalities play more and more critical roles in medical and indus‐ trial domains.

  • Principal component analysis (PCA) and the closely related Karhunen-Lo` ve transe form, or the Hotelling transform, are classic techniques in statistical data analysis, feature extraction, and data compression, stemming from the early work of Pearson [364]. Given a set of multivariate measurements, the purpose is to find a smaller set of variables with less redundancy, that would give as good a representation as possible.

  • The aim of this textbook is to provide a step-by-step guide to financial econometrics using EViews 6.0 statistical package. It contains brief overviews of econometric concepts, models and data analysis techniques followed by empirical examples of how they can be implemented in EViews. This book is written as a compendium for undergraduate and graduate students in economics and finance. It also can serve as a guide for researchers and practitioners who desire to use EViews for analysing financial data.

  • The need for Business Intelligence (BI) solutions and data analysis has always existed, and so have different approaches to fulfill this need. Traditional BI software has heavily relied on techniques that have been around and persisted through the decades, but newer technologies have emerged in recent times that have proven to be more flexible and, therefore, more adequate for the evolving environment in which they are used. QlikView is an example of this kind of disruptive technology, a kind of software that changes the rules of the game. QlikView is different; that's a fact.
