Hi all, I've seen recently this great post by Nikita Murzintcev http://rpubs.com/nikita-moor/107657. If I understood correctly, according to Griffiths (2004) I should select 11 topics? But, it seems that other metrics suggest quite different number of topics?
I mean, 11 topics is about the right number, however, besides it works better in my case, how do I know which metric to rely on? That is, if I want to report this in a paper, can I simply say that I relied on Griffiths (2004), without explaining why not Arun (2010), for example? Thanks,
