AstroStat

AstroStat allows astronomers to use both simple and sophisticated statistical routines on large datasets. This tool uses a large public-domain statistical computing package called R. Datasets can be uploaded in either ASCII or VOTABLE (preferred) format. The statistical computations are performed by AstroStat and results are returned to the user. Only a small portion of R functionality is available through AstroStat. To perform advanced data analysis, users are encouraged to install R locally.
