econirl 0.0.7

Behavioral inference. IRL and DDC with standard errors.

econirl

Structural dynamic discrete choice and inverse reinforcement learning in Python.

EconIRL helps estimate forward-looking choice models, recover reward functions, and evaluate counterfactual policies from panel data.

Documentation: https://econirl.readthedocs.io/

Install

pip install econirl

Quick Start

from econirl.datasets import load_rust_bus
from econirl import NFXP

df = load_rust_bus()

model = NFXP(n_states=90, discount=0.9999, utility="linear_cost")
model.fit(df, state="mileage_bin", action="replaced", id="bus_id")

print(model.params_)

cf = model.counterfactual(RC=4.0)
print(cf.policy[50, 1])

Example output:

{'theta_c': 0.0010028828858836278, 'RC': 3.0722093435989524}
0.05519477716656161

Package Surface

The recommended API is sklearn-style:

from econirl import NFXP, CCP, MPEC, NNES, TDCCP, MCEIRL

Additional estimators and lower-level configuration objects are available under econirl.estimation, econirl.estimators, and econirl.contrib for advanced workflows.
