Hi Mike,
Is there any difference between calculating STTR on the basis of 1000 words and calculating it on the basis of 300 words? I am analyzing texts with different sizes, some of them are very short, so when I calculate the STTR of these texts on the basis of 1000 words, I obtain no result, therefore, I decided to calculate the STTR of ALL texts on the basis of 300 words, and I want to be sure that I am doing it well.
Many thanks,
Najat
