看俩个特征是否存在线性关系。

import pandas as pd

import seaborn as sns

import matplotlib.pyplot as plt

from scipy import stats

train_data='zhengqi_train.txt'

test_data='zhengqi_test.txt'

train=pd.read_csv(train_data,sep='\t',encoding='utf-8')

test=pd.read_csv(test_data,sep='\t',encoding='utf-8')

for col in train.columns:

    print(col)

    sns.regplot(x=col,y='target',data=train)

    plt.show()
