Analysis of Spatiotemporal Characteristics of Pandemic SARS Spread in Mainland China

Figure 5

Spatiotemporal covariance used in the BME modelling. (a) Plot of the empirical spatiotemporal covariance; the covariance was estimated at the nodes shown with small red circles connected with coarse surface plates (the S-lag is in degrees and the T-lag is in days). (b) Spatial cross-section at of the estimated covariance surface and the empirical covariance. (c) Temporal cross-section at of the estimated covariance surface and the empirical covariance. (d) Fitted theoretical covariance plot (densely gridded surface) superimposed on the empirical covariance.
