Abstract:
|
Split plot experiments are becoming increasingly more common in industry. Current research has focused on response surface methodology (RSM) for split plot scenarios. The application of RSM involves a sequential learning strategy. The traditional steps are screening experiments, followed by steepest ascent. After moving through the experimental region, one conducts follow-up experiments. It is important to check that a linear model still holds in these new regions. A common approach is to test for lack-of-fit. This talk will focus on constructing a test for lack-of-fit within a split plot framework.
