Possible 85-95% reduction in stage 2 reweighting time using drop-in-replacement solver in solver.jl

11

I don't know if others have found reweighting to be as slow as I have, but stage 2 reweighing for CPS for 17 years took more than 14 hours on...

FYI: Comparisons of IRS summary statistics for 2017 to puf.csv with: (1) default stages 1, 2, and 3, (2) custom stage 1 growfactors and default stage 2, and (3) version #2 reweighted

You will find the 3 summary report files [here](https://www.dropbox.com/sh/axcicizlg4p7oik/AACqKRkzI4WZqcZvgzixvotfa?dl=0). They should be visible to all. All comparisons are for filers only, as defined in PSLmodels/Tax-Calculator#2501 prior to today (2020-11-06). @MattHJensen...

I don't think the following issue is going to lead me to make adjustments in the short term, at least not until I understand it better, but I wanted to...

version of solver.jl needed to create puf.csv not where taxdata expects it

I haven't yet figured out how to modify Makefile to address #380 so that I can run `make puf-files` (although it works fine for `make cps-files`), so I am running...

Seeking verification of which data files to download and where to put them

3

One reason (perhaps not the only one) I ran into the problem in issue #373 is that I don't have the needed puf and cps files in the right location...

After @andersonfrailey's helpful responses in #373 and #375, and additional changes related to julia that I describe below, `make cps-files` now appears to be working on my ubuntu system, although...

When @MattHJensen, @Peter-Metz, and I were investigating creating state-specific PUFs, we noted that some of the values we were targeting have substantially different national totals reported in our source of...

Improving speed and flexibility of TaxData extrapolation

15

My colleagues @marshallpku, [Gang Chen](https://www.albany.edu/rockefeller/faculty_pad_chen.shtml), and I may have an opportunity to examine TaxData extrapolation for possible speed and flexibility improvements, in preparation to run a large synthetic data file...

Significant issue in running synthetic data through TaxData - seeking advice/help

Of interest to at least the following: @andersonfrailey, @MattHJensen, @martinholmer, @MaxGhenis, @feenberg, @marshallpku, and @gchen3 Despite well-laid plans, we have run into a significant problem running a synthetic version of...

FORCED_STOP from OptimizationNLopt callback returns best point PRIOR to callback, making it unuseful for custom stopping criteria. Is that intended?

2

**Question❓** An OptimizationNLopt solve that results in FORCED_STOP from a callback will return not the point that generated the stop, but the previous best point. Perhaps this is intended, but...
