Dear friends, I am posting a video after some gap! This is our first video in our series on Response Surface Designs. Response Surface Designs become necessary when we want to model a second order response in an experiment. In this first video, Hemant Urdhwareshe explains addition of centerpoint to a factorial design to assess presence of non-linearity in the response. The concept is explained with a virtual catapult with a two-factor two-level design.
