繪製類別因素的交互作用¶
在這個範例中,我們將視覺化類別因素之間的交互作用。首先,我們將建立一些類別資料。然後,我們將使用 interaction_plot 函數繪製它,該函數會在內部將 x 因素類別重新編碼為整數。

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
from statsmodels.graphics.factorplots import interaction_plot
[2]:
np.random.seed(12345)
weight = pd.Series(np.repeat(["low", "hi", "low", "hi"], 15), name="weight")
nutrition = pd.Series(np.repeat(["lo_carb", "hi_carb"], 30), name="nutrition")
days = np.log(np.random.randint(1, 30, size=60))
[3]:
fig, ax = plt.subplots(figsize=(6, 6))
fig = interaction_plot(
x=weight,
trace=nutrition,
response=days,
colors=["red", "blue"],
markers=["D", "^"],
ms=10,
ax=ax,
)
