Unreleased

0.1.0 - 2020-02-03

Changed

  • Model-ready datasets can now be "prediction-only" (i.e. for use pre-election when we don't know results).
  • Model-ready datasets include UKIP and BXP as part of "Other" until a better solution can be found.
  • Various changes to enable a better regional UNS forecast:
    • better handling of NI parties;
    • regional poll-of-polls goes back a month to incorporate large sample regional polling and not just sub-samples;
    • MRP sample sizes are disregarded for weighted poll-of-polls;
    • missing sample sizes (such as for polls derived from PollBase) are imputed using mean sample size within the same region;

Added

  • Merged SixFifty UK polling data (detailed inc. sample sizes) up to June 2017 with Mark Pack's PollBase which has less columns but all polls up to Dec 2019.
  • Incorporated regional polling & regional sub-samples for December 2019 from SixFifty.
  • general-election/UK/2019/model: added model-ready dataset including UNS and regional UNS forecasts for the 2019 UK General Election.

0.0.12 - 2020-02-03

Changed

  • general-election/UK/2015/model: model-ready dataset for just the 2015 UK General Election.

Added

  • general-election/UK/2017/model: model-ready dataset for the 2017 UK General Election.

0.0.11 - 2020-02-02

Added

  • Updated & refactored polling pipeline code.
  • Updated & refactored pipeline for building model-ready datasets for 2015/2017 UK general elections.

0.0.10 - 2020-01-26

Added

  • Raw datasets are now cached on download, and processed datasets cached after processing, and always checked against MD5 for integrity.
  • Tests now exist for utils.py

0.0.9 - 2020-01-26

Added

  • UK 2017 General Election dataset (general-election/UK/2017/results).
  • Some tests (that really need caching!).

Changed

  • Now using data from the House of Commons Library.
  • The basic processed election results are now "long form" with less but more standardised information.
  • The full election results are (for now) no longer provided.
  • Lots of refactoring with some new base classes & utils making it faster to add new datasets.

0.0.8 - 2019-11-14

Fixes

0.0.7 - 2019-11-14

Added

  • Tests added to setup.py.

Changed

  • Switched to using pip-tools instead of Pipenv for generating requirements.txt & locking dependencies.

0.0.6 - 2019-07-13

Added

  • general-election/UK/2015/model: model-ready datasets for the 2015/2017 UK General Elections.
  • Regional polling datasets.

0.0.5 - 2019-07-13

Added

  • Basic tests for get.py
  • Additional processing for the GE2015 results pipeline to generate a more useful dataset for common election modelling tasks.
  • Added general-election/UK/2010/results dataset.

Changed

  • API design for dataset identifiers to use dash/slash instead of underscore/dash and capitalised country codes to make it clearer these will be ISO 3166 Alpha-2 codes, e.g. general_election-gb-2015-results -> general-election/GB/2015/results.
  • Changed GB to UK everywhere as these results are full UK results including Northern Ireland.

0.0.4 - 2019-07-07

Fixes

  • Fixed relative imports and switch to using a class for each dataset.

0.0.3 - 2019-07-07
