Re: [R] fit for truncated normal distribution
On Linux it says "Program received signal SIGFPE, Arithmetic exception". I think the only way to get a SIGFPE (floating point exception) any more (on machines with IEEE floating point arithmetic) is taking an integer modulo zero, which do_druncnorm does when length(x) is 0: const double cx = x[i % n_x]; Should R catch SIGFPE and turn it into an error condition?

Re: [R] fit for truncated normal distribution
I see it in three different Mac builds, including a quite recent local R-devel build. It boils down to this: > dtruncnorm(numeric(0), mean=6.7, sd=1.38, a=-Inf, b=9) Floating point exception: 8 which looks like a bug in the truncnorm package, where dtruncnorm() is unprepared for a zero-length argument. (The indirect cause is fitdistrplus:::test1fun, which makes calls like the above.) -pd > On 14 Mar 2020, at 19:42 , Bert Gunter wrote: > > Inline. > > Bert Gunter > > "The trouble with having an open mind is that people keep coming along and > sticking things into it." > -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) > > > On Sat, Mar 14, 2020 at 10:36 AM |Juergen Hedderich > wrote: > >> Dear R-help list members, >> >> the R Session aborted without any 'comment' for the following 'small >> example': >> >> /library(fitdistrplus) >> library(truncnorm) >> >> filter <- c(4.98, 8.60, 6.37, 4.37, 8.03, 7.43, 6.83, 5.64, 5.43, 6.88, >> 4.57, 7.50, 5.69, 7.88, 8.98, 6.79, 8.61, 6.70, 5.14, 7.29) >> >> fit <- fitdist(filter, "truncnorm", fix.arg=list(a=-Inf, b=9), >> start=list(mean=mean(filter), sd=sd(filter)), >> optim.method="L-BFGS-B", >> lower=c(-0.1, -0.1), upper=c(Inf, Inf))/ >> >> R worked fine in an 'older' R-version (environment).
