Figure 2: Flour Beetle Growth Example. (a) Fitted trajectories using warped ANOVA model; (b) warping functions; (c) principal component of the main factor, ˆ φ ( t ) (solid line), and of the residual term, ˆ ψ ( t ) (dashed line); (d) estimated mean ˆ µ ( t ) (solid line), ˆ µ ( t ) + ˆ φ ( t ) (dash-dot line), and ˆ µ ( t ) − ˆ φ ( t ) (dotted line). 28
