FIGURE 2.

Dataset partition for $r=5$ years in the future. The boxes indicate which years the covariates are measured ($t‐h+1,\dots ,t$), and the arrows point to the year at which we predict infestation ($t+r$). So the length of each box represents $h$ and the length from the box to the arrow represents $r$. Green solid lines represent the training dataset whereas blue dashed lines represent the testing dataset. From top to bottom: 1‐, 2‐, 4‐, and 5‐year history‐length
