SPSS Statistics is a statistical software suite developed by IBM for data management, advanced analytics, multivariate analysis, business intelligence, and criminal investigation. Long produced by SPSS Inc., it was acquired by IBM in 2009. Current versions (post 2015) have the brand name: IBM SPSS Statistics.

The software name originally stood for Statistical Package for the Social Sciences (SPSS),[3] reflecting the original market, then later changed to Statistical Product and Service Solutions.[4][5]
SPSS is a widely used program for statistical analysis in social science.[6] It is also used by market researchers, health researchers, survey companies, government, education researchers, marketing organizations, data miners,[7] and others. The original SPSS manual (Nie, Bent & Hull, 1970)[8] has been described as one of "sociology's most influential books" for allowing ordinary researchers to do their own statistical analysis.[9] In addition to statistical analysis, data management (case selection, file reshaping, creating derived data) and data documentation (a metadata dictionary is stored in the datafile) are features of the base software.
Additionally a "macro" language can be used to write command language subroutines. A Python programmability extension can access the information in the data dictionary and data and dynamically build command syntax programs. The Python programmability extension, introduced in SPSS 14, replaced the less functional SAX Basic "scripts" for most purposes, although SaxBasic remains available. In addition, the Python extension allows SPSS to run any of the statistics in the free software package R. From version 14 onwards, SPSS can be driven externally by a Python or a VB.NET program using supplied "plug-ins". (From Version 20 onwards, these two scripting facilities, as well as many scripts, are included on the installation media and are normally installed by default.)
The graphical user interface has two views which can be toggled by clicking on one of the two tabs in the bottom left of the SPSS Statistics window. The 'Data View' shows a spreadsheet view of the cases (rows) and variables (columns). Unlike spreadsheets, the data cells can only contain numbers or text, and formulas cannot be stored in these cells. The 'Variable View' displays the metadata dictionary where each row represents a variable and shows the variable name, variable label, value label(s), print width, measurement type, and a variety of other characteristics. Cells in both views can be manually edited, defining the file structure and allowing data entry without using command syntax. This may be sufficient for small datasets. Larger datasets such as statistical surveys are more often created in data entry software, or entered during computer-assisted personal interviewing, by scanning and using optical character recognition and optical mark recognition software, or by direct capture from online questionnaires. These datasets are then read into SPSS.
Several variants of SPSS Statistics exist. SPSS Statistics Gradpacks are highly discounted versions sold only to students. SPSS Statistics Server is a version of SPSS Statistics with a client/server architecture. Add-on packages can enhance the base software with additional features (examples include complex samples which can adjust for clustered and stratified samples, and custom tables which can create publication-ready tables). SPSS Statistics is available under either an annual or a monthly subscription license.
SPSS Statistics version 13.0 for Mac OS X was not compatible with Intel-based Macintosh computers, due to the Rosetta emulation software causing errors in calculations. SPSS Statistics 15.0 for Windows needed a downloadable hotfix to be installed in order to be compatible with Windows Vista.
SPSS Data Collection and SPSS Dimensions were sold in 2015 to UNICOM Systems, Inc., a division of UNICOM Global, and merged into the integrated software suite UNICOM Intelligence (survey design, survey deployment, data collection, data management and reporting).[19][20][21]
IDA (Interactive Data Analysis)[22] was a software package that originated at what formerly was the National Opinion Research Center (NORC), at the University of Chicago. Initially offered on the HP-2000,[23] somewhat later, under the ownership of SPSS, it was also available on DEC's DECSYSTEM-20.[24] Regression analysis was one of IDA's strong points.[23]

Requirements Engineering: Elicitation Techniques PDFAffifa KanwalThis paper is about the elicitation methods for requirement collection. Requirements engineering initial step is the most key phase of the software development life cycle (SDLC). If the first step in conducted in wrong way the whole project may fall down. The elicitation techniques are used to eliminate the barriers in communication of the user and the requirement engineers. In this paper we examine the strategies connected to name the necessities. We attempt to know the flaws and plus points of these practices and come up to a convenient or suitable technique amongst them.
Big Data Analytics Landscape And Careers PDFMr. Vikas ChauhanBig Data Analytics helps organizations harness their data and use it to identify new opportunities. That, in turn, leads to smarter business moves, more efficient operations, higher profits and happier customers. $15 billion on software firms only specializing in data management and analytics. This industry on its own is worth more than $100 billion and growing at almost 10% a year which is roughly twice as fast as the software business as a whole. In February 2012, the open source analyst firm Wikibon released the first market forecast for Big Data, listing $5.1B revenue in 2012 with growth to $53.4B in 2017. The McKinsey Global Institute estimates that data volume is growing 40% per year, and will grow 44x between 2009 and 2020.
An Ensemble Framework for Software Defect Prediction PDFShiwang AgarwalDefect Prediction is a very necessary tool in the maintenance and durability of software. It increases durability, reduces cost and most important efforts. It increases the efficiency of the software. In this paper, a verifiable study is done to analyse the performance and durability of software.
Analysis of a 7-storied RC Building with Different Patterns of Cross Bracing System PDFCaptain Sheikh Rifat Iftekhar, Ehsanul Kabir, Tasnuva FarnazIn this study, the seismic analysis of reinforced concrete (RC) buildings with different bracing patterns namely, no bracing, full bracing, partial bracing, alternate floor bracing and alternate partial bracing is studied. The bracing is provided for peripheral columns and any two parallel sides of building model. A seven-storey (mid-rise) residential building situated in Dhaka city is analyzed for seismic zone II as per BNBC 2006 using ETABS 9.6.0 and ANSYS 10.0 softwares. 2ff7e9595c
