Changes in version 2.4.3 (2021-11-17)                  

  - Bug fix, thanks to Patrik Schilter. The B1B2 component of the
    function pnbd.pmf.General defined in R/pnbd.R has changed. The fix
    is that the third parameter of the B2 function described by equation
    (24) here is now correctly set to c <- r + s + x + 1. The previous,
    incorrect version carried over the i component from the first term
    by setting c <- w + x + 1.

                 Changes in version 2.4.2 (2020-12-12)                  

  - Now hardie defaults to TRUE everywhere but in bgndb.generalParams,
    where it defaults to NULL
