Parse contest_table.csv and print contest, choice, precinct
Parse and print contest, choice, precinct
As run on Orange County 2018 primary LAT file. Fix contest counts
add --minprecinctcount Sort contests by sequence they are noticed in Does need (Vote for=1) Add BallotType column fix number of columns in line 4
also default minprecinctcount to "max number of precincts"
parse_hart.py: calculate, export outcomes, assuming all are 2-winner contests analyze_rounds.py: parse all_contest_audit_details_by_cvr.json import outcomes calculate risk levels for all winner-loser pairs doesn't audit risk of single-winner via majority yet
Fix call to sampler.generate_outputs() in publish_ballots_to_audit Finish get_county_cvrs() Also: For each audited cvr, show imprinted_id, not db_id Exit on upload failure reasons, explain why Fix bug in get_county_dashboard() acvr default Streamline logging of upload progress Switch from 30 second interval for progress uploads to 3 New arg: '--progress-delay', Time to pause between upload progress queries. Default 3.0. Fix some broken cvr and acvr download examples
Incorporate changes from crtest in November
main.py --ballot-polling-tally: temporary hard-coded random distribution of ACVR choices from 2016 presidential election. --num_samples: limit number of ACVRs entered analyze_rounds.py: handle divide-by-zero, improve comments, test data in contest_table_test.csv simple test script in bptest.bash
parse_hart.py --cvr_contests option to filter out a subset of contests for CVR. Deal with overflow in ballot_polling_risk_level More documentation and transparency for bpatest.bash
And update comments and TODOs
This was referenced Jun 10, 2018
parse_hart: Default to 2000-ballot CVRs, with margin of 7 to get about 1092 ballots audited to start, more possible. skip non-selected contests Use tsv output format in analyze_rounds, and limit to just selected contests Allow analyze_rounds without exports argument fix audit_cvrs branch name shorter lines in README.md fix some TODO comments show outright majority sample sizes and risks use ballot_polling_risk_level from rlacalc, delete the one in analyze_rounds.
And provide number of ACVRs entered.
Porting was just a one-line change :)
refactor out outright_risk() and loop fore each candidate Need to compute risk of reporting incorrect outright win for each candidate Fix indentation bug, looking at wrong winner
The sample size calculation needs the margin specific to the given risk calculation New Risk_record class to collect necessary info, format in consistent way Output for a given contest is now all collected together with more details Switch to python3 for types.SimpleNamespace

Add some python scripts (
