[BobBorges]

Revitalizing old issue welfare-state-analytics/riksdagen-corpus#265.

• construct test file with party distribution in parliament over time
  • unikameral period (wikpedia/wikidata)
  • bicameral period (Stjernqvist Tvåkammartiden 1996:122-123
• test that mp metadata reflects test file

Fredrik will ask Lotta to get a source about party distribution for the unicameral period

[fredrik1984]

We should only do a party distribution test for the time when there were "real" parties in the parliament (ca 1900–)

[fredrik1984]

For the unicameral period, Lotta suggested that we use election statistics from Statistics Sweden:

https://www.statistikdatabasen.scb.se/pxweb/en/ssd/START__ME__ME0104__ME0104C/Riksdagsmandat/

From the link above, we can get party distribution data from 1973 and onwards.

For the relevant bicameral period (1912–1969), we use Stjernquist 1996 (p. 123).

Sure. I can probably fix this for the unicamwral period.

Now fixed unicameral period test data in #37
