Calculating Achievable Upper Bounds
main topic  

When you change the default lower bounds of one component, the achievable upper values on the other components are also adjusted downward. Specifically, the achievable upper bound (Ui) for component i is

Ui = Total for mixture - [L1 +  L2 +  ... +  L ( i-1) +  L( i+1) + ... +  Lq] where L is the lower bound

Minitab prints out both the specified lower bounds and achievable upper bounds in the Session window output. As an example, suppose you have 3 components and you entered 10 in Total Mixture Amount in the Components subdialog box. If you entered the following lower bounds, L1 = 0, L2 = 2 and L3 = 1, then the achievable upper bounds are U1 = 7, U2 = 9 and U3 = 8.
