[EM] Spatial models -- Polytopes vs Sampling

[Colin Champion]

I haven't followed this discussion - sorry if I'm missing something. I 
quite like Jameson Quinn's model of an infinite number of dimensions of 
progressively diminishing importance. On the other hand, if 'n 
dimensions' is understood as meaning n dimensions of equal importance, 
then it seems to me intuitively unattractive. As a first approximation I 
might describe politics on a left/right axis; as a second I might 
distinguish between economic and social liberalism but expect them to be 
correlated (leading to a cigar-shaped 2D Gaussian) etc. (This doesn't 
help Daniel who wants an upper limit.)

Quinn's model is on his vse page:
