Methodology of European Studies Quantitative European Studies on the bases of STATA and R Aleksandra Parteka & Joanna Wolszczak-Derlacz With the support of the LPP programme of the European Union 2

STATA statistical software - is a complete, integrated statistical package, used in quantitative research, application: mainly in economics, social sciences and medicine. THE SOFTWARE IS NOT FREE OF CHARGE www. stata. com With the support of the LPP programme of the European Union 3

STATA CAPABILITIES • • • Data management Statistical and econometrical analysis Graphics Simulation Statistical programming Matrix programming—Mata With the support of the LPP programme of the European Union 4

How it works? • Working with databases possibility of migration data from xls, txt and other formats • has an easy-to-use point-and-click interface providing access to its commands. • Stata also has a simple, consistent command syntax. • Both operations and their results are recorded and repeatable.

Advantages of the program STATA • ability to work with large databases • easy to combine data from different sources • a command can replace hundreds of individual operations built-in commands • the ability to download the command-mini programs of other users • fast and "smart" With the support of the LPP programme of the European Union 8

• „do” files - used to create your own mini-programs able to return to the entire sequence of operations, to modify them and repeat the entire path of operations with a single click • „log” files - through the log files that all operations were performed and their results will be stored ("write operation of the session") With the support of the LPP programme of the European Union 10

R is both a programming language, the name of development platform equipped with an interpreter of the language and the name of the project, within which a language and environment for statistical computing and graphics is developed. R is a free software http: //www. r-project. org/ With the support of the LPP programme of the European Union 13

R Installation 1. Installer file: (R-2. 12. 2 -win. exe) 2. http: //cran. rproject. org/mirrors. html 3. 2. The ‘bin/windows’ directory of a CRAN site contains binaries for a base distribution and a large number of add-on packages from CRAN to run on Windows XP 4. 3. R packages are installed into libraries, which are directories in the file system containing a subdirectory for each package installed there.
