Thank you for your response. I saw already that example and some others too. However, they defined alpha and beta in the examples or use two different dataset. I did not know alpha and beta values and have only one data set. I could calculate alpha and beta by using variance and means for the data has one peaks.
How can I calculate alpha and beta for two peak distributions?
