VM TTR values

[Koen G]

Hi Marco, I used the function =STANDARDIZE, which uses mean and stdev. It is very likely that someone on the forum once recommended this to me, though I don't remember the exact context. 

If I understand correctly, 0 is the mean of the corpus. So a text that behaves average for all windows I measured will be a line on 0. Above 0 is above average (like Latin), below zero is below average. 

Since the corpus might be imbalanced, I don't think we should take the position of lines compared to 0 into account. But I find this the best way to visualize and compare different texts with each other. If we don't normalize, the differences at the critical small windows will be hard to see.

Edit: also, these are all values I measured: 3 5 8 12 15 20 30 50 75 100 150 250 500 1000
