For example, when you run a Gage R&R, the last result that shows up in the session window is a value for the ‘Number of Distinct Categories’. This one metric is something that customers seem to overlook when they call to discuss their Gage studies. This value represents the number of groups your measurement tool can distinguish from the ...The possible number of superkeys is 2 (n-k). Example 11: Let a relation R have attributes {a1,a2,a3_____ an} such that any k of the attributes at a time determines all other attributes. Find the value of k such that the number of candidate keys in the relation will be maximum. Any k attributes at a time constitute one candidate key.You use exponents in r when you have a number that you want to raise to a power. R has two commands that are capable of doing exponents and they both produce exactly the same results. So, deciding which one to use is purely a matter of personal taste. Because these two commands produce the same result you can use whichever one you want.
