![]() R first appeared in 1993 and was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand.Documentation and books tend to be very technical and not necessarily new user friendly.Since SAS is a proprietary software, there may be an extensive lag time for the implementation of new methods.Graphics can be cumbersome to manipulate.Size of datasets analyzed is only limited by the machine.With one procedure, test results, post estimation and plots can be produced.SAS has two main types of code DATA steps and PROC steps.Predominantly used for data management and statistical procedures.Multitude of additional components are available to complement Base SAS which include SAS/GRAPH, SAS/PH (Clinical Trial Analysis), SAS/ETS (Econometrics and Time Series), SAS/Insight (Data Mining) etc. ![]() SAS Libraries collect the SAS datasets you create.BASE SAS contains the data management facility, programming language, data analysis and reporting tools.ODS Graphics Designer provides a more interactive interface.Can be cumbersome at times to create perfect graphics with syntax.csv), SPSS (.sav), Stata (.dta), JMP (.jmp), Other (.xml) In 2012, SAS held 36.2% of the market making it the largest market-share holder in 'advanced analytics.' The National Institute of Health funded this project with a goal of analyzing agricultural data to improve crop yields.The development of SAS (Statistical Analysis System) began in 1966 by Anthony Bar of North Carolina State University and later joined by James Goodnight.Stata schemes, however, provide some flexibility in changing the style of the graphs. Overall, graphs have limited flexibility.One may have to sacrifice the number of variables for the number of observations, or vice versa, depending on the package. The specific Stata package ( Stata/IC, Stata/SE, and Stata/MP) limits the size of usable datasets.Can only hold one dataset in memory at a time.Works well with panel, survey, and time-series data.Some user written programs are available to install. ![]() ![]()
