In this chapter I cover the foundations of probabilistic mixture modeling, from the marginalization of categorical variables to numerically stable implementations and inferential degeneracies. Along the way I also discuss the discrete and continuous inflation models.

If you need a distraction tomorrow then note that you can still register for my four hour hierarchal modeling course, https://t.co/0gL69z9oRv. All you need to do is make a donation to one of two charities doing important work in Gaza right now.

<looks around apprehensively> So everyone is going to take all of this polling skepticism and critique and apply it to analyses in their own field, perhaps even their own analyses, right? RIGHT?

A great reminder not to take arrows in diagrams for granted: what do they mean? what assumptions do we make about them? how reasonable are these assumptions? what happens if they fail?

I'm still trying to find a good term for studying the range of behaviors in data simulated from a model. I'd appreciate feedback on a few candidates, https://t.co/cPKHdoAYrj.

Damn, my upcoming hierarchical modeling short course next week, https://t.co/0gL69z9oRv, has raised over 2000 USD for World Central Kitchen and Doctors Without Borders. There's still time to join and spread the word.
