Impedance Functions by Education Level for Census Divisions

Impedance functions fitted to commuting duration distributions for Canadian Census Divisions (CDs), categorized by education level. Functions were estimated using the fitdistrplus package based on PwDUR (commuting duration) data from the 2021 Census of Population. The best-fit distribution was selected using the lowest AIC.
