mirrored listing x402 eip155:8453

Fits ordinary least squares to log radiance by year, converts the slope to annual radiance

Fits ordinary least squares to log radiance by year, converts the slope to annual radiance change, and applies a caller-supplied economic elasticity. Night lights are an imperfect proxy affected by sensors, saturation, electrification, outages, policy, and conflict; this is not an official economic statistic or causal estimate.
