pdf of two distribution in mixture

How should i get pdf of 2 mixture beta and gamma if we have given mean =2 a=4,b=7 ? i have generated random variable

Answer 1

[Jeff Miller]

the pdf of the mixture is just the weighted average of the pdfs of the beta and gamma, something like

p_beta = 0.8;  % probability of beta
X = 0.1:0.01:1;  % whatever X range you want
mixpdf = p_beta*betapdf(X,{beta parameters go here}) + (1-p_beta)*gampdf(X,{gamma parameters go here})

But i dont have X range i have just random data

[Lakshit Chugh]

i have dataset of 500 x 1

[Jeff Miller]

OK, X can be your random data if you want the pdf's of those random data values.

I am pretty sure that I don't really understand what you are actually trying to compute.

[Lakshit Chugh]

actually i am trying to find histogram density and kernel density can you help me with that ?
