Total EffectΒΆ

We use lingam package:

import lingam

Then, we create a DirectLiNGAM object and call the fit() method:

model = lingam.DirectLiNGAM()

To estimate the total effect, we can call estimate_total_effect() method. The following example estimates the total effect from x3 to x1.

te = model.estimate_total_effect(X, 3, 1)
print(f'total effect: {te:.3f}')
total effect: 21.002
