Hi, Full disclosure, I'm not a mathematician so I can not go into the weeds into the math. However I am tasked with porting some matlab code that is doing gaussian mixed model to java. I really want to use apache common math if possible. However the code that I'm porting has 1 dimension ( a single variable/attribute/property) that GMMs are being created from.
MultivariateNormalMixtureExpectationMaximization looks to be a pretty close drop in replacement for the matlab functions https://www.mathworks.com/help/stats/fitgmdist.html<https://www.mathworks.com/help/stats/fitgmdist.html> andhttps://www.mathworks.com/help/stats/gmdistribution.html, however the constructor for MultivariateNormalMixtureExpectationMaximization clearly states the the number of columns in the double[][]data array MUST be no less thatn2 columns. I'm completely baffled as to why this is the case if I want to try to fit data with 1 dimension in it. Is there a workaround I can use like provide a dummy column of data with all 0s to pacify the constructor? Is there another class I should be using? Any help would be greatly appreciated.
