Simple python code to calculate Posterior Total Causal Effect (PostTCE) and Posterior Direct Causal Effect (PostDCE).

Description

Variables: cause variables $X=(X_{0},...,X_{p-1})$ and effect variable $Y$

k: int, ${0,1,...,p-1}$

Obs: np.array, observed evidence $[x_0,...,x_{p-1},y]$ where y=1 and x_{i} in {0,1,np.nan}

Pr_joint: numpy.ndarray, joint probability, Pr_joint[x[0],...,x[p-1],y] = $\Pr(X_{0}=x_0,...,X_{p-1}=x_{p-1},Y=y)$
