generating random numbers from mixed beta gamma distribution

Hi I want to create custom distribution (mixed distribution ) between beta and gamma then

generate random numbers from this distribution

is there a specific code for that??

Thanks in advance

Here is one way to do this with Cupid

% Create a custom mixture distribution:
% Use whatever distribution parameters and mixture probability you want.
mybeta = Beta(5.3,4.1);
mygamma = RNGamma(17,10);
mycustom = Mixture(.3,mybeta,.7,mygamma);  % .3 is the probability of mybeta

mycustom.PlotDens;  % Plot the PDF and CDF of the custom distribution

myrands = mycustom.Random(100,1); % generate 100 random numbers.

Cupid? Its not even Valentine's day yet.

"Continuous Univariate Probability Distributions"

Even though there are some discrete ones in there, I didn't want to call it "STandard Univariate Probability Distributions".

Hi

It gives undefined function or variable 'Mixture'

any suggestion will be helpful

thanks in advance

There must be some problem with the download/installation from GitHub. Do you see the file Mixture.m in the same folder with Beta.m and RNGamma.m (and all the other files)? You should. Also, MATLAB must see these files, you must either point MATLAB to this folder or put this folder on the MATLAB path.
