py4project
授業向けの分析・可視化ユーティリティです。pandas DataFrame から回帰分析・散布図・折れ線グラフ・横バープロット・ボックスプロット・円グラフを簡単に作成できます。
インストール
pip install py4project
提供している関数
regression(x, y, data, ...)— 回帰分析(xにリストを渡すと重回帰)。決定係数・係数・p値・信頼区間を表にして表示し、結果オブジェクトを返しますregression_plot(x, y, data, ...)— 散布図+回帰直線(regressionの結果を渡すこともできます)scatter_plot(x, y, data, ...)— 散布図+トレンド線(対数軸オプションあり)bar_plot(x, data, ...)— 横バープロット(複数系列・シフトシェア分解の配色に対応。label_colで縦軸の名前、sort_byで並び順、legendで凡例の名前を指定)box_plot(x, data, ...)— ボックスプロット(対数化オプションあり。label_colを指定すると外れ値に名前を表示)line_plot(x, y, data, ...)— 折れ線グラフ(yにリストを渡すと複数系列を重ねて表示)pie_plot(x, data, label_col, ...)— 円グラフ(パーセント表示。topやotherで小さい項目をまとめられます)
使用例
import pandas as pd
from py4project import regression, bar_plot
df = pd.DataFrame({
"産業": ["製造業", "卸売業", "小売業", "建設業"],
"事業所数": [120, 80, 60, 40],
"従業者数": [1500, 900, 700, 380],
})
# 回帰分析(セルの最後に置くと結果表が表示されます)
regression("事業所数", "従業者数", df)
# 横バープロット
bar_plot("従業者数", df, label_col="産業", title="産業別の従業者数")
