from formative import DAG

dag = DAG()
dag.assume("proximity").causes("education")
dag.assume("ability").causes("education", "income")
dag.assume("education").causes("income")

result = IV2SLS(
    dag,
    treatment="education",
    outcome="income",
    instrument="proximity"
).fit(df)

print(result.summary())
