Fit Ordinary Least Squares (OLS) regression.
Epochs
| iterable of SourceEstimate
The data to be regressed. Contains all the trials, sensors, and time points for the regression. For Source Estimates, accepts either a list or a generator object.
ndarray
, shape (n_observations, n_regressors)The regressors to be used. Must be a 2d array with as many rows as the first dimension of the data. The first column of this matrix will typically consist of ones (intercept column).
None
Optional parameter to name the regressors (i.e., the columns in the
design matrix). If provided, the length must correspond to the number
of columns present in design matrix (including the intercept, if
present). Otherwise, the default names are 'x0'
, 'x1'
,
'x2', …, 'x(n-1)'
for n
regressors.
dict
of collections.namedtuple()
For each regressor (key), a namedtuple is provided with the following attributes:
beta
: regression coefficients
stderr
: standard error of regression coefficients
t_val
: t statistics (beta
/stderr
)
p_val
: two-sided p-value of t statistic under the t distribution
mlog10_p_val
: -log₁₀-transformed p-value.
The tuple members are numpy arrays. The shape of each numpy array is
the shape of the data minus the first dimension; e.g., if the shape of
the original data was (n_observations, n_channels, n_timepoints)
,
then the shape of each of the arrays will be
(n_channels, n_timepoints)
.
