mixture experiment and cost function
Hello,I have a mixture data with ingredients I_1, I_2, ... I_9. They add up to 1 as this is a mixture data. The response is y. Of the 9 ingredients 6 of them have cost associated with them, say I_1 - I_6. I creates a new column: C = p1*I_1 + p2*I_2 + ... + p6*I_6. This gives the total cost per unit weight. Now I run a mixture response surface model for y. But when I go to optimize it, I like to ta...
