From: Exploring the longitudinal dynamics of herd BVD antibody test results using model-based clustering
Longitudinal clusters of the shapes of farm antibody PP trajectories with cluster means fitted as nonlinear function of time. The dotted lines are individual farm trajectories; bold lines are mean of the trajectories in each component. The x-axis represents the four time period of the study (2007–2010), y-axis are the standardized (shape) values of the antibody PP values.
