I run fitgmdist on some data (total of 40 instances/samples) and and get a two-component Gaussian Mixture Model with ComponentProportion containing an array of two values: 0.8927 and 0.1073. Using the cluster method on the resulting gmdistribution, and passing in the original 40-element array, it returns an array of cluster IDs, 36 of which have the value "1", and 4 of which have the value "2". My expectation was that ComponentProportion would have contained exactly [0.9, 1.0] to reflect the ratios of cluster IDs in the data being fit. But apparently that’s not the case. Can anyone tell me where the actual ComponentProportion values come from? Thanks.I run fitgmdist on some data (total of 40 instances/samples) and and get a two-component Gaussian Mixture Model with ComponentProportion containing an array of two values: 0.8927 and 0.1073.
