I have a dataset that is composed of data points from three clusters. Suppose the data points in the mth (m = 1,2,3) cluster follow iid N(μm,σm2 Ip) where p is the dimensionality of the data. Each data point has two dimension. (x1, y1)
I want to Implement a DA algorithm (Gibbs sampler) to cluster these data points into three groups. Can anyone help me to implement that .
Thanks so much.

Hi,

I would greatly appreciate if you can help me on this.

You may want to look at "help gmdistribution.fit" if you have the Statistics Toolbox.
