Linear Trend in EDA

[Eichhof]

Hey

Do you know if the cvxEDA algorithm already removes linear trends? I think linear trends should not be a problem for phasic components but for tonic components.

Or else should we detrend the raw EDA data before running cvxEDA?

@Eichhof It does implement some form of trend correction (I believe it's more complex than a simple linear detrend tho). This algorithm was built and tested on raw data.

Thanks for your answer. So you mean cvxEDA or your library implements some form of trend correction?

[DominiqueMakowski]

I mean that the cvxEDA algorithm (present in neurokit but mostly copied from here) does itself everything necessary and can be used with raw data
