[R] Fitdistrplus package : Error messages

[Rui Barradas]

Hello,

This is because you have non-integer values in vector x?


This one works.

##Poisson distribution
f2p <- fitdist(floor(x), "pois")
plot(f2p)
summary(f2p)


Not so well

##negative binomial distribution
f2n <- fitdist(floor(x), "nbinom")
f2n <- fitdist(ceiling(x), "nbinom")
f2n <- fitdist(round(x), "nbinom")

plot(f2n)
summary(f2n)


Hope this helps,

Rui Barradas
