Estimation of spread in a group of registered knee angle curves from a 13-year old child with spastic diplegia. The left column depicts the standard deviation bands with (top graph) and without (bottom graph) an apparent outlying curve (thin dashed line). The 90% bootstrap prediction bands are plotted on the right, again with (top graph) and without (bottom graph) the outlying curve.
