Re: [R] Function for Distribution Fitting
"all possible probability distributions" I doubt that is a finite set. To select "a bunch of them" would seem to imply a reduction of that set based on what's possible/promising/pertinent in your specific problem. IMHO, what's the "most suitable distribution" tends to depend partly on knowledge of the subject matter of your problem. Doesn't that put you back in your present situation? ---JRG On 10/26/22 09:41, Paul Bernal wrote: > Dear friends from the R community, > > Hope you are all doing great.

Don't use as.integer(), which has performed precisely the service that
it advertises?
I certainly wouldn't call this an 'inadequacy'.
And please stop posting in html.

Re: [R] long integer handling
The largest consecutive integer that can be represented in double
precision is 2^53.
You'll have to move past double precision.
