Jul 06, 2016 · I have a problem of fitting individual gaussians after a Gaussian mixture model fitting. The means and sigmas for the individual gaussians are obtained from fitgmdist. Hi, i am begginer with matlab. i plot two histograms. I can plot one of them continiously (figure1), but i can't plot another one continiously (figure2). This example shows how to simulate data from a multivariate normal distribution, and then fit a Gaussian mixture model (GMM) to the data using fitgmdist.To create a known, or fully specified, GMM object, see Create Gaussian Mixture Model.

Use the gmdistribution function to create a gmdistribution object by specifying the distribution parameters. Use the fitgmdist function to fit a gmdistribution model to data given a fixed number of components. This post clued me in that the PDFs I calculated integrated to 1 individually (rather than together), but I'm unsure how to obtain the "non-integrated" components of the mixture model such that I can plot them to match the original plot. pd = fitdist(x,distname,Name,Value) creates the probability distribution object with additional options specified by one or more name-value pair arguments. For example, you can indicate censored data or specify control parameters for the iterative fitting algorithm. The problem is that fitgmdist() computes a very narrow distribution to be more robust (to the point where there is no overlap). When we extend the range to include distribution overlap we are undoubtedly including skew from the non-normal convergence. Then we performed a Gaussian Mixture Model fit to data using fitgmdist() function and simulated a contour plot from the fitted parameters. Afterwards, we customized the contour plot to better display the fitted results. How to plot statistical data from MATLAB's Statistical Toolbox.
