[split] Percentage of word types that occur more than once

[Alin_J]

This is also not unusual, at least not for non-English works... I found that the Swedish novel Inferno by August Strindberg has a number of 4.38 (total number of words about 46 000).

What's this ratio of? hapaxes or word types?

Not hapaxes. This is just the ratio of total number of words to word-types (in other words the inverse of Type-Token Ratio).

Thanks. Was this done on the French original or the English translation?

Not the French original, but the Swedish translation (by Eugène Fahlstedt).
