distributions – Does mathematica have support for mixture models?

Does Mathematica have support mixture models? Similar to the R language libraries mclust or mixtools. The documentation for mixtools is quite good.

The closest support I can find in Mathematica is the LearnDistribution[] function as documented here. I can get a PDF out of this, but I cant figure out how to get parameter estimates out, or to define the number of distributions it should determine, or define any start conditions.
