Quadratic Models with Inputs that change X-Position of Vertex
Hi JMP Community, I have a response variable that goes from 0 to 100% and following a quadratic function in response to a continuous variable. The vertex of which can only go up to 100%. The problem I'm having is that there's a nominal factor that can shift this function to the left and to the right. So far, I've filtered for responses to less than 80% to make the regression mostly linear (2nd ord...
