75a48a3c
In UD v2.15 (largest treebank per language, punctuation excluded, 156 languages with >=50 projective sentences), observed dependency length is significantly below a random projective-linearization baseline (D_obs<D_rand) by a per-corpus Monte-Carlo randomization test at p<0.05 with R=100 random projective linearizations per sentence, in 148/156 languages (94.9%); 152/156 minimize in the mean (mean D_obs/mean D_rand < 1).
