mne.stats.linear_regression: can epochs be the independent variable?

With mne.stats.linear_regression
(http://mne-tools.github.io/stable/generated/mne.stats.linear_regression.html),

epochs are is passed to a numpy.linalg.lstsq
(https://github.com/mne-tools/mne-python/blob/a7d3c208813732321aff4a4d7c853bf149653604/mne/stats/regression.py#L119)

as the dependent variable
(https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.linalg.lstsq.html).

Is there a way to run mne.stats.linear_regression with the epochs as the
independent variable?

Thanks,
