RALSA v.0.90.1 was released!
We are proud to announce the first release of RALSA. After all the hard work of development, the first version of the R Analyzer for Large-Scale Assessments (RALSA) came to life. RALSA targets both the experienced R users, as well as those who do not have technical skills. Thus, along with the traditional command-line R interface, a Graphical User Interface is made available.
Welcome to the website of the R Analyzer for Large-Scale Assessments
The R Analyzer for Large-Scale Assessments (RALSA) is an R package for preparation and analysis of data from large-scale assessments and surveys which use complex sampling and assessment design. RALSA is a free of charge and open source software licensed under GPL v2.0 and is cross-platform — it works on any system which can run a full installation of R. Currently, RALSA supports a number of studies with different design and a number of analysis types (see below). Both of these will increase in future.
