mne.stats.ttest_ind_no_p¶
- mne.stats.ttest_ind_no_p(a, b, equal_var=True, sigma=0.0)[source]¶
Independent samples t-test without p calculation.
This is a modified version of
scipy.stats.ttest_ind()
. It operates along the first axis. Thesigma
parameter provides an optional “hat” adjustment (seettest_1samp_no_p()
and 1).- Parameters
- aarray_like
The first array.
- barray_like
The second array.
- equal_varbool
Assume equal variance. See
scipy.stats.ttest_ind()
.- sigma
float
The regularization. See
ttest_1samp_no_p()
.
- Returns
- t
array
T values.
- t
