Help! I’m trying to fratar (iterative proportional fitting, raking) a 58 by 58 commuter matrix using R packages. I could use some help. Attached are my initial scripts and input database to create the 58 by 58 “seed” matrix (2012-16 CTPP, Total Workers, Table A302100). I’m just a little mystified as to how to implement the raking/frataring given the different IPF packages available: Ipfp, mlfit, mipfp, rakeR, rake…… My goal is to rake the 58 by 58 county-to-county total commuters for California, using the 2012/2016 CTPP to estimates of individual years: 2012, 2013, 2014, 2015, 2016.

Reminder: CTPP users survey - please participate

by Mohammadian, Abolfazl

Dear Colleague, Thanks to those who have already completed the survey. In case you overlooked the first email (and you are a transportation professional in the U.S.), please consider participating in this short survey<https://uic.ca1.qualtrics.com/jfe/form/SV_dolfGg2cMOoCuTY>, even if you are not a frequent CTPP user. I am helping AASHTO to understand how best to serve Census transportation data users. The survey<https://uic.ca1.qualtrics.com/jfe/form/SV_dolfGg2cMOoCuTY> takes about 15 minutes to complete. All of your responses will be private and will only be presented in aggregate format. FYI, the CTPP is a State DOT-funded, cooperative program that produces special tabulations of American Community Survey (ACS) data that have enhanced value for transportation planning, analysis, and strategic direction. This study<https://uic.ca1.qualtrics.com/jfe/form/SV_dolfGg2cMOoCuTY> is the first step to understand data utilization by the users’ community as well as determining the gaps in CTPP products that can be addressed by introducing new tables. Here is the link to the questionnaire: https://uic.ca1.qualtrics.com/jfe/form/SV_dolfGg2cMOoCuTY Best Regards, Kouros --------------------------------------- Abolfazl (Kouros) Mohammadian, PhD Professor and Department Head Civil, Materials, and Environmental Engineering University of Illinois Chicago Co-Editor in Chief, Transportation Letters Associate Editor, Transportation Research Record Email: kouros(a)uic.edu<mailto:kouros@uic.edu> Twitter: @K_Mohammadian<https://twitter.com/K_Mohammadian> ---------------------------------------
