  1. Do you know what the pdf of the Mandel h statistic is?

    • If you look at the expressions for the different statistics used in significance testing – see link on this page:

      Other statistical inspection methods of measured values

      – you can see some likenesses between them. Thus the Mandel h statistic is quite similar to the well-known t-statistic. One might thus also expect some similarity between their pdfs. Wikipedia has a clear description of the pdf of the t-statistic .
