用python对两个样本进行尺度检验的代码

以下是使用Python进行两个样本尺度检验的代码示例：

使用SciPy库中的ttest函数进行t检验：

from scipy.stats import ttest_ind

sample1 = [1, 2, 3, 4, 5]
sample2 = [2, 4, 6, 8, 10]

t_statistic, p_value = ttest_ind(sample1, sample2)

print("t statistic:", t_statistic)
print("p value:", p_value)

使用NumPy库中的var函数和chi2函数进行方差齐性检验：

import numpy as np
from scipy.stats import chi2

sample1 = [1, 2, 3, 4, 5]
sample2 = [2, 4, 6, 8, 10]

var1 = np.var(sample1)
var2 = np.var(sample2)

df = len(sample1) + len(sample2) - 2
chi2_critical = chi2.isf(q=0.05, df=df)

if var1 / var2 > 1:
    f_statistic = var1 / var2
else:
    f_statistic = var2 / var1

if f_statistic > chi2_critical:
    print("The variances are different.")
else:
    print("The variances are the same.")
