NIST PT Analysis Program

The NIST PT analysis program can be downloaded here

The program is written in R and is run using the open source R-Software. The program compares the result of a given machine with the results of all other machines that tested using the same series of NIST SRM verification specimens.

For directions on running the NIST analysis, refer to the information provided for "running the program." You will need the R-Software, the NIST PT analysis program, and the Data file(s) with the relevant test results. At this point you can run the NIST PT analysis program and get results for your machine.
