Hello,
I have data; one column and 310 rows. When I plot the histogram, it has two
peaks; please see the attachment. I would like to find appropriate
distribution that fits the data. I tried to mixtools in R, but it did not
fit well.
I want to mix two beta distribution. I found that there is betareg package
in R but the shape1,shape2 were known or there were two different data in
the all examples.
I do not know where to start. How can I use betamix in R to fit the data?
Any hint?
I really appreciate.
Thank you

Searching on "beta mixture model in r" leads to a number of hits, the
most relevant one (it seems to me) being:
r - Mixture of beta distributions: full example - Cross Validated
which leads to

A fully worked example is provided.
cheers,
