Bayesian Time Varying Coefficients in PYMC3

GDP Growth Rates

Okay so today I want to talk about something really cool that you can do with time-series / panel data. That is, you can allow the coefficients in the model change over time. It is a really neat idea, but […]

Learning XOR with Only Linear Regression (Yeah it’s Possible)

Alright, so that title isn’t very clickbaity unless you are a real data nerd. Linear models do terrible at learning XOR. Simply because XOR is highly non-linear. It requires a non-linear model to learn it. And my model is non-linear […]

Predicting March Madness Winners with Bayesian Statistics in PYMC3!

So in the last two blog posts, I talked about how to do some bayesian inference in the realm of some linear models. And that is all well and good, but we can have even more fun in a bayesian […]

Bayesian Logistic Regression in Python using PYMC3

In my last post I talked about bayesian linear regression. A fairly straightforward extension of bayesian linear regression is bayesian logistic regression. Actually, it is incredibly simple to do bayesian logistic regression. If you were following the last post that […]
