Combining factorials
WebA combination is any unique selection (or subgroups) from the group, where a permutation considers the order of those selections. We can use the letters in the word MATH as an example. If we were to find all of the different combinations of 2 letters, we would have 6 possibilities: MA,MT,MH,AT,AH,TH. In this case, the MA is the same as AM ...

Abstract: In many practical experiments, both the level combinations of factors and the addition orders will affect the responses. However, virtually no construction methods have been provided for such experimental designs.
Web21. Two fairly simple suggestions: To avoid overflow, do everything in log space. Use the fact that log (a * b) = log (a) + log (b), and log (a / b) = log (a) - log (b). This makes it easy to work with very large factorials: log (n! / m!) = log (n!) - log (m!), etc. Use the gamma function instead of factorial. WebNote how I was able to cancel off a bunch of numbers in the previous problem. This is because of how factorials are defined — namely, as the products of all whole numbers between 1 and whatever number you're taking the factorial of — and this property can simplify your work a lot by allowing you to cancel off everything from 1 through whatever …
