Hello,

I?m trying to fit distributions to data. To do this, I used the function ?fitdist? from the fitdistrplus package and I drew a Cullen and Frey graph (attached Figure 1). From this graph, I am attempting to fit different distributions: Beta, Gamma and Weibull. The function ?fitdist? works with Gamma distribution from this code:

Fit.dist <- fitdist(x[x!=0], distr="gamma", method="mle",lower=c(0, 0),start=list(scale=1,shape=1))

However, with Beta and Weibull distributions, I obtain this error message:

  the function mle failed to estimate the parameters,

                with the error code 100

Here is my code to fit Beta and Weibull distributions:

fit.dist <- fitdist(x_scaled, distr="beta", method = "mle")

fit.dist <- fitdist(x, distr="weibull", method="mle", lower=c(0, 0))

For the Beta distribution, I transformed the variable to have values between 0 and 1 as follows:

x_scaled  <- (x-min(x))/max(x)

Here are some information about data (summary() and attached Figure 2)
