[R] Estimating Mean of a Poisson Distribution Based on Interval censoring

Generally with SAS it may be that R is correct or just that R and SAS use slightly different algorithms.

[R] Estimating Mean of a Poisson Distribution Based on Interval censoring
Fortune candidate :-) However, the more scientific approach would be to ask for evidence to be scrutinized, acknowledging that R might be fallible, however unlikely that may seem. Also, there is always the possibility that there are two answers because the question is not the same. -pd> On 14 Feb 2016, at 14:35 , John Kane <jrkrideau at inbox.com> wrote: > >> By the way, is there anything for lognormal?I think fitdistcens is not >> good for this purpose as it gives me different result compared to SAS > > The general assumption is that if Excel or any other spreadsheet gives a result that is different from R then R will be correct. > > Generally with SAS it may be that R is correct or just that R and SAS use slightly different algorithms. > > John Kane > Kingston ON Canada > > >> -----Original Message----- >> From: r-help at r-project.org >> Sent: Sat, 13 Feb 2016 08:45:02 +0000 (UTC) >> To: r-help at r-project.org >> Subject: [R] Estimating Mean of a Poisson Distribution Based on Interval >> censoring >> >> Dear all, >> I appreciate that if you let me know if there is any package implemented >> in R for Estimating Mean of a Poisson Distribution Based on Interval >> censoring?
