hi Jesse,
Makes sense, indeed, fixing code internals vs understanding the pain points of model building are two entirely different things, and a power-user is probably the only way to go.
I’m really keen about finance and I love backtesting and implementing algorithmic trading strategies and research papers. Interestingly, I tried to take an applied approach recently while Ethan did his ADVI Trainer for streaming (PR #8333). For the sake of stress-testing his out-of-core pipeline on non-stationary data, I made a regime-switching volatility benchmark notebook (2-state HMM on 100k equity-style returns). It turned out to be a good exercise that showed the limitations of mean-field ADVI on temporal structures.
Taking your advice, I would like to spend some time being a better user of PyMC and building new notebooks that utilizes pymc-extras.statespace in connection with trading concepts, like a Kalman filter-based pairs trading strategy or time-varying beta.
Since my goal is to thoroughly prepare for the upcoming GSoC session (specifically under State Space Models project), are there any specific papers or resources on state-space models applied to econometrics/finance that you’d recommend I read?
I’d love to spend the next few months studying the underlying math and building applied notebooks. I plan to share the models I build here on Discourse to get your critiques and feedback as I learn, so I can eventually contribute more meaningfully.
