R help - Feb 2023 - identify the distribution of the data

Dear all,

I do have dataframes with numerical values such as 1,9, 20, 51, 100 etc

Which way do you recommend to use in order to identify the type of the
distribution of the data (normal, poisson, bernoulli, exponential,
log-normal etc ..)

Thanks so much,

Bogdan

1. This is a statistical question, which usually is inappropriate here:
this list is about R language (including packages) programming.

2. IMO (so others may disagree), your question indicates a profound
misunderstanding of basic statistical issues. While maybe you phrased it
poorly or I misunderstand, but "identify the type of distribution" is
basically a meaningless query. Explaining why this is so and what may be
more meaningful would require a deep dive into statistics. You might try
referencing a basic statistical text and/or online tutorials. Try searching
on "Goodness of fit", "statistical modeling" or the like.

Cheers,
Bert

Hi

Others gave you more fundamental answers. To check the possible distribution
you could use package

https://cran.r-project.org/web/packages/fitdistrplus/index.html
