WebFeb 19, 2024 · MATLAB functions use Sigma in Multivariate Normal, and this is covariance matrix. The gmdistribution class uses Sigma for covariance matrix. So if you extract the diagonal elements out of that, you have variances. But pdf uses sigma, i.e., standard deviation. Note:You'll have to check whether gmsigma (2) gives you the (1,2) element of ... WebOct 10, 2014 · So what I would do in your case is create a new GMM model trained on the entire dataset ( X1, X2, and X3) with the number of components equal to the total sum of all components from the three GMM (that is 2+1+3 = 6 Gaussian mixtures). This model would be initialized using the parameters of the individually trained ones.

WebJan 18, 2024 · For now I am looking for the mean, and the std deviation of each mode. I found that fitgmdist could give the mean of each mode but when I use fitgmdist matlab changes the data to a histagram, so the modes are no longer centered around 2, 10, and 20 but now they are centered around 0.5, and 5 after that.
