Each ghost statistic has a bimodal distribution, with one peak ~70 for ‘high’ stats and one ~30 for ‘low’ stats.
High stats correlate with other high stats: many ghosts have either all stats high or all stats low. This suggests a distinction between e.g. ‘Major’ spirits (which tend to have all stats high, but sometimes have a few low) and Minor spirits (vice versa).
Sliminess seems to be the stat most correlated with major/minor-ness: almost all Major spirits have high Sliminess, and almost all Minor spirits have low Sliminess. Hostility is the least correlated: Hostile Minor spirits, or non-Hostile Major spirits, both happen relatively often.
However, I haven’t yet been able to come up with anything clever to do with this, and ended up mostly just using a linear regression.
Results of my analysis:
Most exorcists have one particular ghost stat that seems to primarily govern the difficulty they face:
The Phantom Pummelers really do not like Sliminess.
The Spectre Slayers really do not like Intellect.
The Wraith Wranglers really do not like Hostility.
The Demon Destroyers really do not like Grotesqueness (and also do better with low Hostility).
while some behave differently:
The Entity Eliminators seems to dislike all stats, especially Sliminess: perhaps they have a hard time with Major spirits and a relatively easy time with Minor ones?
The Mundanifying Mystics have a very high base rate, but actually charge slightly less for all stats—they are expensive in general, and get extra annoyed when you waste their time with Minor spirits?
We handle the idiosyncracies of hiring the various exorcists:
Paying the Demon Destroyers to come seems worth it: they might actually save us 400sp in expectation just on spirit W alone.
The Spectre Slayers seem more valuable than the Entity Eliminators: while the Eliminators are all-around okay at minor spirits, with our knowledge of who is good against which stats we can always pick out a better exorcist to use, while the Spectre Slayers are a uniquely good bet for spirits like S that have very low INT but high other stats.
There are exactly three spirits where I think the Pummelers save us money (N, U, and a little bit on H), so we don’t need to fret about that constraint.
And we end up assigning (unless I find something else to do and change this):
We appear to have done pretty much the exact same things—identified the major/minor spirit distinction, not found anything to do with it, just fed the stats into a linear regression—and gotten the exact same answer.

Edit after seeing simon’s answer:
We appear to have done pretty much the exact same things—identified the major/minor spirit distinction, not found anything to do with it, just fed the stats into a linear regression—and gotten the exact same answer.
(And I wonder which ghost your great-uncle is...perhaps we can get away with sending no exorcist at all to that one?)
