About Statistical Bases
A statistical basis is a set of variable values you want to use to calculate the distribution of an allocation, such as the employee headcount in each company department or the square footage of real estate you rent in each location. You can save the values you have entered for reuse later.
If you update the values set on an existing statistical basis, the previous version is saved for reference purposes and the new version used in all subsequent allocations that use that statistical basis.
