I have some data (x) and want to determine which distribution fits them best. I used:
descdist(x, discrete = FALSE, boot = 1000) fit.norm<- fitdist(x, "norm") plot(fit.norm) fit.norm$aic
and did the same for weibull, gamma and lnorm. In the documentation I could not find a list of which other distributions (and the corresponding syntax) are possible. Does anyone know where I can find this information?
From the FAQ you get if you type ??fitdistplus
As documented, we provide initial values for the following distributions: norm
, lnorm
, exp
, pois
, cauchy
, gamma
, logis
, nbinom
, geom
, beta
, weibull
from the stats package; invgamma
, llogis
, invweibull
, pareto1
, pareto
from the actuar package.
Documentation also suggests you can use any distribution if you can specify it or find it in a pre-existing package.
Add on to @Jacob's answer, here are two documentation pages I found really helpful where both the distribution names and the R syntax can be seen.
