Nothing is better than asking help to find the answer by myself... Page 47 of the technical report (tr504.pdf) deals exactly with the problem of big datasets. Also I found that mclust is too much for my problem, the optimum number of Gaussian suggested is way too high. For example for one dat

Hi all! I have an ordered vector of values. The distribution of these values can be modeled by a sum of Gaussians. So I'm using the package 'mclust' to get the Gaussians's parameters for this 1D distribution. It works very well, but, for input sizes above 100.000 values it starts taking really
