Beta distribution- help needed
Hi,
Well, i need some help, practical and theoretical. I am wondering why the
fitdistplus (mle function) is returning an error for this code:
[code]
x1 <- c(100,200,140,98,97,56,42,10,2,2,1,4,3,2,12,3,1,1,1,1,0,0);
plotdist(x1);
descdist(x1, boot =1000);
y<- sum(x1);
d= as.vector(length(x1));
for(i in 1:length(x1)){
d[i] = x1[i]/y;
}

Error:
Error in fitdist(d, "beta") :

fitting a distribution to a ecdf plot
Dear all,
I need to plot an cumulative distribution plot of a variable and then to fit a distribution to that, probably a weibull or lognormal.
I have plotted the ecdf as
> plot(ecdf(x))
but I haven't managed to fit the distribution. I have as well attached the data.
I would appreciate if you could help me on that.
Thank you.
Kind regards
Maria
