Python多元线性回归寻找p值

Question

我需要找到pvalue。为了一个出口。但是，我不能使用import statsmodels.formula.api as sm。它给我带来了一个错误：（有没有不使用statsmodels就可以找到pvalue的方法？这就是我目前所拥有的。你知道吗

import numpy
from scipy.stats import pearsonr
data = numpy.genfromtxt("2-2.4.txt",delimiter=",")
x = data[:,6]
x2 = data[:,7]
x3 = data[:,8]
x4 = data[:,9]

y = data[:,-1]  


r, p = pearsonr(x,x2,x3,x4, y) # how do I find the pvalue when working with multiple variables

导入时statsmodel出错
