Table 6 Mean bias and root-mean-square error of the Puglia sampling strategy simulation with a logistic function for different points of origin of the simulated disease spread and fitted with Gallipoli as assumed origin (see Supplementary Analysis 3).

From: Shape and rate of movement of the invasion front of Xylella fastidiosa spp. pauca in Puglia

Simulation point of origin

Mean bias (km/year)

RMSE (km/year)

Gallipoli

− 0.039

0.53

Santa Maria di Leuca

− 6.73

7.76

Otranto

− 4.16

Maglie

− 2.36

  1. RMSE root-mean-squared error.
  2. Bias is the average difference between the estimated value and the true value of the rate of movement of the front in km/year.
