(raw, decim_fit=100)¶Regress out MEG ref channels
Computes linear models from MEG reference channels on each sensors, predicts the MEG data and subtracts and computes the residual by subtracting the predictions.
Note
Operates in place.
Note
Can be memory demanding. To alleviate this problem the model can be fit on decimated data. This is legitimate because the linear model does not have any representation of time, only the distributions matter.
