MATTR added to the Lexical Diversity Calculator
Last week, I implemented the calculation of MATTR (Moving Average TTR) into the Lexical Diversity Calculator. MATTR calculates the mean TTR for successive windows of a text (Covington & McFall, 2010), getting, at least that is the idea, a more stable indication of lexical diversity. While that’s not entirely the case (see Bestgen, 2025), you can still test it at https://www.reuneker.nl/ld.

Next: implementing a compression-rate measure to operationalize text repetiveness for what hopefully becomes a project together with Vivien Waszink!
