XVal is a Windows program that contains instruments for cross validating statistical models. This method is used to partition data into complementary subsets and iteratively train the system.
Main purpose
This application is built around the family of generalized linear models and encompasses many different analysis methods. The main function is easily adapted to any other statistical operation that has estimation and prediction properties.
Running in parallel
Like in TASSEL, users can perform cross validation with the help of multiple cores on one processor or by utilizing several machines that access the same network drive. However, the overhead of handling a large number of computers may become a performance bottleneck.
Advanced options
It is possible to set custom values for the starting and finishing iterations. There are tools for forcing the recalculation, computing the sum of the spillpoint mask grids, outputting an HTML activity report and performing a wide variety of other tasks. The full list of all possible commands and arguments with detailed descriptions is available in the official documentation.
