If we consider a 3-dimensional Gaussian series with three changes at times 120, 320 and 400 specified by


1) x_1 increases
2) x_1 decreases, x_2 increases
3) x_2 decreases, x_3 increases

we get the following results for our posterior "z-scores" of the logistic regression coordinates:

Here’s a video my wife (not on bsky) captured of the cranes just enjoying life:

If you want an easy-to-use Python package for interpretable multivariate, multiple changepoint detection with uncertainty quantification, check out BCLR, now on PyPI: pypi.org/project/bclr/
