Design and Analysis of Experiments capable of doing, it±s reasonable to consider fundamental changes to its analysis of experiments," with the goal of eventually addressing complex situations where there are many "process knobs" (factors), each with multiple settings (levels) and thus many many potential ways that things could important factors.

The Big Problem modules. The noisy process output y is a/ected by variables x 1 , x 2 , x 3 and potentially other variables (both recognized and unrecognized). The question is how to set up the "control panel" (the settings of the "knobs" or values of some variables x 1 , x 2 , x 3 ) to collect data and e¢ ciently learn how to optimize the process to get desired values of y .

Samples from r Di/erent Experimental Conditions We begin with a most basic experimental scenario, where one has data consisting of observed responses, y , for some number, r , di/erent ll write y ij = the j th response in sample i (made under the i th set of process conditions) where sample sizes are n 1 , n 2 , . . . , n r .
