I'm currently having a hard time understanding the adjoint of the cumsum operator and while trying to understand it, I've encountered something. In line ```281 - 283``` in ```tvregdiff.py```, the...

BUG: Numerically incorrect `scipy.signal.savgol_coeffs` (also affects `scipy.signal.savgol_filter`)
## Basic Problem When I ran a grid search for optimizing the Savitzky-Golay filter parameters, I found that for high `polyorders`, the coefficients from `scipy.signal.savgol_coeffs` are numerically incorrect (see **Reproducing...
This pull request - adds an initial version of a `Makefile` with basic commands, i.e., installation, build, lint checks, individual and parallelized testing (also mentioned in the new `Development` section...
With a simple `Makefile` commands like `make test` could be used to trigger all the tests with the correct specifiction of arguments instead of a very long command like `pytest...
This pull request primariliy tackles issue #44, but it does not fully close it (see the second point of **🚶 Next Steps**). It should be squashed before merging because it's...
## 🚶➡️🏃 Proposed Enhancement We could add a super general purpose estimator that integrates the [`pybaseline`](https://pybaselines.readthedocs.io/en/latest/index.html) package for elaborate baseline correction. The package is great and offers a variety of...
## 🚶➡️🏃 Proposed Enhancement Today, I [answered this StackExchange Question](https://stats.stackexchange.com/a/648154/365558) on the Savitzky-Golay filter and thereby I figured out that the automated selection of the Savitzky-Golay (and thus the mean...
### 🚶➡️🏃 Proposed Enhancements In some spectroscopic fields like UV/Vis- or MIR-spectroscopy (of liquid systems), peaks can show very strong overlap. This limits the usefulness of many spectroscopic analysis techniques,...
## 🚶➡️🏃 Proposed Enhancement In 2023, some researchers put the Savitzky-Golay-filter to the test and figured out that - despite its wide-spread use - it is actually far from being...
