Best practice in FDE when the main variation is a shift along X (phase variation) rather than a change in shape?
Hello JMP community, I have been testing Functional Data Explorer on a synthetic data set where each curve is essentially the same motif translated along the X-axis, with little intrinsic change in amplitude or shape. In this situation, my impression is that the resulting FPCA/FPC basis becomes increasingly oscillatory, and the physical interpretation becomes difficult. In other words, one simple...
