Fit an AR model to raw data and creates the corresponding IIR filter.
The computed filter is fitted to data from all of the picked channels, with frequency response given by the standard IIR formula:
An instance of Raw.
Order of the FIR filter.
Channels to include. Slices and lists of integers will be interpreted as
channel indices. In lists, channel type strings (e.g.,
'eeg']) will pick channels of those types, channel name strings (e.g.,
['MEG0111', 'MEG2623'] will pick the given channels. Can also be the
string values “all” to pick all channels, or “data” to pick data
channels. None (default) will pick good data channels. Note that channels
info['bads'] will be included if their names or indices are
