Vassili Savinov
great episode. really appreciated the coverage of standard error. one missed opportunity, imho, was slapping a prior on that likelihood to get a posterior, and thus connecting to Bayesian stats
Vassili Savinov
great episode. could have been connected to Bayesian stats better
Vassili Savinov
you managed to explain visual path tracing in audio-only setting. Amazing, thanks!
Vassili Savinov
hit it with a bigger MC hammer - love it. on a more serious note, this episode was great at making me think deeper about logistic regression.

Amazing episode. Convergence to impossible solutions does happen. Hosts gave a couple of great solutions for dealing with it
