I'm a music researcher and wondered if there is a branch of statistics that could help with a question I have. Telemann is a composer I work with a lot, and there are apparently about 125 orchestral suites that survive, but most of them survive in three unique libraries spread around Germany: Darmstadt, which has the bulk of them, then Dresden, then Schwerin). Historically we know there are missing suites because while the music doesn't always survive, there are musical catalogues with incipits.
Is there anyway using statistics, we can get an estimate of how many total missing suites there are? What would be the methods of getting that number?
