Summary
[edit]A naive PELT changepoint using ruptures to detect when the time-series encountered a shift. You'll see that this is pretty naive - we even include the COVID period. If we naively remove it, we get a changepoint around Jan 2024. ruptures has a bunch of other changepoint detection algos and you can use them to see that all of them get the Nov 2023 to Jan 2024 period as significant. Curious result.
