[split] Word length autocorrelation

[quimqu]

But doing line by line as I did, its mean is negative (about -0.07).

I get 0.169 for word bigrams all in the same line (positive-negative)/(positive+negative). I used all the lines (including labels) of the old Takahashi transliteration (ivtff_v0a).

No, what I did is entire words. The goal is to see if one word after the other has the form [short-long-short] or [short-short] / [long-long]
