Sum counts #33

Open rouzbeh opened 2 years ago

rouzbeh commented 2 years ago

This PR fixes a suspected bug. It seems that counts should be summed over each minute, and not averaged. The current counts are not integers, which doesn't seem to be correct.

I think this is an oversight, but please check!

Hi @rouzbeh, you are totally right, this formula is wrong! Additionally, the values should be summed over 1 sec instead of 1 min to match the output in the paper by Brond et al.. I am about to update the code accordingly. If it's desired to accumulate the activity counts even more (e.g., to epochs of 30s or 1min), I will add a utility function. However these changes will also affect other parts of biopsykit, especially the biopsykit.sleep.sleep_wake_detection module, which we're currently working on and which will be ready soon. I will create a new release once we're finished with the rework!

Hi @richrobe . That's good to know. You may also be interested in agcounts, which is a python package published by ActiGraph and replicating our counts algorithm. A paper will be published soon about this.

thanks for the hint, I'll check it out! I'm also happy to have a look at your paper as soon as it's published 🙂
