@bodiyang please see my PR to your branch where I create a json file to handle indexed parameter rounding for the round trip reform.

@bodiyang I remaining incorrect parameter values for EITC_ps_MarriedJ and just opened a PR to your branch with that fix.

@MattHJensen There's a lot here and I don't want to miss something again. Can you put another set of eyes on this PR and let me know if there are still years out of order or if we failed to correct anything noted in Issues #2647, #2649, #2651 and now Issue #2655?

Thanks for your work on this @bodiyang!

Merging despite a failure when testing on Windows with Python 3.7. Error looks like an idiosyncratic issue with connecting to Codecov.io
