What is ReGenesees

ReGenesees (R Evolved Generalized Software for Sampling Estimates and Errors in Surveys) is a full-fledged R software for design-based and model-assisted analysis of complex sample surveys. This system is the outcome of a long term research and development project, aimed at defining a new standard for calibration, estimation and sampling error assessment to be adopted in all large scale sample surveys routinely carried out by Istat (the Italian National Institute of Statistics).

System Architecture

ReGenesees has a clear-cut two-layer architecture: the application layer of the system is embedded into an R package named ReGenesees. A second R package, called ReGenesees.GUI, implements the presentation layer of the system (namely a Tcl/Tk GUI). Both packages can be run under Windows as well as under Mac, Linux and most of the Unix like operating systems. While the ReGenesees.GUI package requires the ReGenesees package, the latter can be used also without the GUI on top. Thus the statistical functions of the system will always be accessible by users interacting with R through the traditional command-line interface. On the contrary, less experienced R users will take advantage from the user-friendly mouse-click GUI.

Data Input/Output

The ReGenesees system can import data in a variety of ways. First, it can load R workspace files (with .RData or .rda extensions) storing previously saved data. Second, data can be imported from Text Files (with extensions .txt, .csv, .dat). Third, the system can import data from MS Excel spreadsheets and/or MS Access database tables. Currently, ReGenesees can save output data into R workspace files (.RData, .rda) and/or export them into Text Files (.txt, .csv, .dat). Further extensions are possible.
