  • An Introduction to the SAS System
    An Introduction to the SAS System Dileep K. Panda Directorate of Water Management Bhubaneswar-751023 [email protected] Introduction The SAS – Statistical Analysis System (erstwhile expansion of SAS) - is the one of the most widely used Statistical Software package by the academic circles and Industry. The SAS software was developed in late 1960s at North Carolina State University and in 1976 SAS Institute was formed. The SAS system is a collection of products, available from the SAS Institute in North Carolina. SAS software is a combination of a statistical package, a data – base management system, and a high level programming language. The SAS is an integrated system of software solutions that performs the following tasks: Data entry, retrieval, and management Report writing and graphics design Statistical and mathematical analysis Business forecasting and decision support Operations research and project management Applications development At the core of the SAS System is the Base SAS software. The Base SAS software includes a fourth-generation programming language and ready-to-use programs called procedures. These integrated procedures handle data manipulation, information storage and retrieval, statistical analysis, and report writing. Additional components offer capabilities for data entry, retrieval, and management; report writing and graphics; statistical and mathematical analysis; business planning, forecasting, and decision support; operations research and project management; quality improvement; and applications development. In general, the Base SAS software has the following capabilities A data management facility A programming language Data analysis and reporting utilities Learning to use Base SAS enables you to work with these features of SAS. It also prepares you to learn other SAS products, because all SAS products follow the same basic rules.

La palabra es especialmente problemática porque su traducción al inglés, “free”, es aun más polisémica, e incluye el concepto “gratis”. En 1985 se fundó la Free Software Foundation (FSF) para defender una definición rigurosa del sófguar libre. La propia palabra “sófguar” (del inglés “software”, por oposición a “hardware”, quincalla, aplicado al soporte físico de la informática) es en sí misma problemática.

  • Cumulation of Poverty Measures: the Theory Beyond It, Possible Applications and Software Developed
    Cumulation of Poverty measures: the theory beyond it, possible applications and software developed (Francesca Gagliardi and Giulio Tarditi) Siena, October 6th , 2010 1 Context and scope Reliable indicators of poverty and social exclusion are an essential monitoring tool. In the EU-wide context, these indicators are most useful when they are comparable across countries and over time. Furthermore, policy research and application require statistics disaggregated to increasingly lower levels and smaller subpopulations. Direct, one-time estimates from surveys designed primarily to meet national needs tend to be insufficiently precise for meeting these new policy needs. This is particularly true in the domain of poverty and social exclusion, the monitoring of which requires complex distributional statistics – statistics necessarily based on intensive and relatively small- scale surveys of households and persons. This work addresses some statistical aspects relating to improving the sampling precision of such indicators in EU countries, in particular through the cumulation of data over rounds of regularly repeated national surveys. 2 EU-SILC The reference data for this purpose are EU Statistics on Income and Living Conditions, the major source of comparative statistics on income and living conditions in Europe. A standard integrated design has been adopted by nearly all EU countries. It involves a rotational panel, with a new sample of households and persons introduced each year to replace one-fourth of the existing sample. Persons enumerated in each new sample are followed-up in the survey for four years. The design yields each year a cross- sectional sample, as well as longitudinal samples of 2, 3 and 4 year duration.

  • Comparison of Three Common Statistical Programs Available to Washington State County Assessors: SAS, SPSS and NCSS
    Washington State Department of Revenue Comparison of Three Common Statistical Programs Available to Washington State County Assessors: SAS, SPSS and NCSS February 2008 Abstract: This summary compares three common statistical software packages available to county assessors in Washington State. This includes SAS, SPSS and NCSS. The majority of the summary is formatted in tables which allow the reader to more easily make comparisons. Information was collected from various sources and in some cases includes opinions on software performance, features and their strengths and weaknesses. This summary was written for Department of Revenue employees and county assessors to compare statistical software packages used by county assessors and as a result should not be used as a general comparison of the software packages. Information not included in this summary includes the support infrastructure, some detailed features (that are not described in this summary) and types of users.
