Your eigenranking lab

In this computer lab for linear algebra, you’re going to apply the eigenrating technique to a league of four teams each pair of which plays once.

Your data

To get the games for your league, choose your name from the following list:

viewof name = { 
    const names = d3.sort( 
        ["---", "Jordan","Gabriel","Jacob S","Lexi","Carlos","Amina","Doug","Lauren","Miranda","Collin","Leo","Sal","Bryan P","Audrey","Estelle","Zachary","Fin","Bryan M","Lilia","Isabel","Jacob C","William","James"]
    ).map((name,idx) => ({name,idx}));
    return Inputs.select(names, {format: o => o.name});
}

{
    if(name.idx > 0) {
        const games = generate_season(name.idx);
        const good_games = games.map(function (game) {
            const good_game = ({});
            if(game.score1 < game.score2) {
                good_game.WTeam = game.team2;
                good_game.LTeam = game.team1;
                const wscore = game.score2;
                const lscore = game.score1;
                good_game.WScore = wscore;
                good_game.Lscore = lscore;
            }
            else {
                good_game.WTeam = game.team1;
                good_game.LTeam = game.team2;
                const wscore = game.score1;
                const lscore = game.score2;
                good_game.WScore = wscore;
                good_game.Lscore = lscore;
            }
            return good_game
        });
        return md`${toMarkdownTable(good_games)}`
    }
    else {
        return md``
    }
}

Your next task

Once you’ve got your data, you’ll analyze it in Colab. I’ll show you how Audrey would do her version here:

• Blank notebook
• Finished version

function toMarkdownTable(games) {
  if (!games.length) return "";

  // Get headers from the keys of the first object
  const headers = Object.keys(games[0]);

  // Build the header row and the separator row
  const headerRow = `    | ${headers.join(" | ")} |`;
  const separatorRow = `    | ${headers.map(() => "---").join(" | ")} |`;

  // Build the data rows
  const dataRows = games.map(
    game => `    | ${headers.map(h => game[h]).join(" | ")} |`
  );

  // Join everything together
  return [headerRow, separatorRow, ...dataRows].join("\n");
}
