The GRIMMER test is an extension of the GRIM test and allows for testing measures of variability in addition to means. Through a mathematical discovery I am able to quickly check whether statistics of any size and precision are mathematically possible.
Rounding issues and how computers store numbers can affect the accuracy of the test. See the help page for more details.
A preprint detailing how the test works is available here.
