Overview-Of-Statistical-Analytics-And
Brief Overview of Statistical Analytics and Machine Learning tools for Data Scientists Tom Breur 17 January 2017 It is often said that Excel is the most commonly used analytics tool, and that is hard to argue with: it has a Billion users worldwide. Although not everybody thinks of Excel as a Data Science tool, it certainly is often used for “data discovery”, and can be used for many other tasks, too. There are two “old school” tools, SPSS and SAS, that were founded in 1968 and 1976 respectively. These products have been the hallmark of statistics. Both had early offerings of data mining suites (Clementine, now called IBM SPSS Modeler, and SAS Enterprise Miner) and both are still used widely in Data Science, today. They have evolved from a command line only interface, to more user-friendly graphic user interfaces. What they also share in common is that in the core SPSS and SAS are really COBOL dialects and are therefore characterized by row- based processing. That doesn’t make them inherently good or bad, but it is principally different from set-based operations that many other tools offer nowadays. Similar in functionality to the traditional leaders SAS and SPSS have been JMP and Statistica. Both remarkably user-friendly tools with broad data mining and machine learning capabilities. JMP is, and always has been, a fully owned daughter company of SAS, and only came to the fore when hardware became more powerful. Its initial “handicap” of storing all data in RAM was once a severe limitation, but since computers now have large enough internal memory for most data sets, its computational power and intuitive GUI hold their own.

Thus in June of 1933, the ASA and the Social Science Research Council officially created the Committee on Government Statistics and Information Services (COGSIS) to serve the statistical needs of the Agriculture, Commerce, Labor, and Interior departments … COGSIS set … goals in the field of federal statistics … (It) wanted new statistical programs—for example, to measure unemployment and address the needs of the unemployed … (It) wanted a coordinating agency to oversee all statistical programs, and (it) wanted to see statistical research and experimentation organized within the federal government … In August 1933 Stuart A. Rice, President of the ASA and acting chair of COGSIS, … (became) assistant director of the (Census) Bureau.

An Overview of Recent and Emerging Developments in PLS-SEM
CHAPTER 1 An Overview of Recent and Emerging Developments in PLS-SEM LEARNING OUTCOMES 1. Understand the origins and evolution of PLS-SEM. 2. Comprehend the principles of and recent developments in measurement. 3. Get to know the essential differences between PLS-SEM and CB-SEM and understand when to use each method. CHAPTER PREVIEW In recent years many developments have occurred in partial least squares structural equation modeling (PLS-SEM). Among the most prominent was the latest release of the SmartPLS software (Ringle, Wende, & Becker, 2015). User-friendly software makes social sci- ences scholars much more efficient and effective in reaching their Draft Proofresearch and- Dopublication not goals. copy, This is especially post, true when or the distribute software includes options to complete the most up-to-date analyses possible with a particular statistical method. 1 Copyright ©2018 by SAGE Publications, Inc. This work may not be reproduced or distributed in any form or by any means without express written permission of the publisher. 2 Advanced Issues in Partial Least Squares SEM In this chapter, we first provide an overview of the origins and evolution of PLS-SEM to establish a foundation for better under- standing why the method was slow to be adopted but has been increasingly applied in recent years across many social sciences disciplines, particularly the various fields of business administration. We then summarize the software that facilitates easy application of this rapidly emerging technique and briefly highlight recent method- ological developments in PLS-SEM. To understand how PLS-SEM differs from covariance-based SEM (CB-SEM), we then discuss dif- ferent approaches to measure conceptual variables and highlight which method is more suitable for selected model types.
