Using the first method, the PCA yields 3 or maybe 4 components. We'll use 4.
Then we need to create a new dataset with placeid year as the panel, so that we can run between regressions. One issue was that some observations have a missing avgdisthm even when layer=chosenhulllayer. This was because in some cases there was only one geometry. In a similar vein, avghulldisthm is the distance between hull geometries, not within hull geometries, so is missing when there are zero or one hulls. In both cases, we flag the instances (using variables onegeom, onehull, zerohull) and then replace missings with zero (as this is conceptually correct).
