graph LR;
A-- a1 --> B1 -- b1--> B2 -- b2 --> C;
A -- a2 -->B2;
B1 -- b3--> C;
A--> |c'| C;

\(B1 = \beta_0 + a_1 \cdot A + e_i\)

\(B2 = \beta_0 + a_2 \cdot A + b_1 \cdot B1 + e_i\)

\(C=\beta_0 + c' \cdot A + b_3 \cdot B1 + b_2 \cdot B2 + e_i\)

Pathways

\(a_1 \cdot b_1 \cdot b_2\)

\(a_2 \cdot b_2\)

\(a_1 \cdot b_3\)
