如何在Python中打印列名称以及Logistic回归的列协同效应？

Question

logreg = LogisticRegression()

logreg.fit(X_train,y_train)

print(logreg.coef_ )
print(X.columns)

如何使用列名压缩logreg.coef_ long？ 谢谢:)

Answer 1

这是一种方法：

# Create lists
column_labels = X.columns.tolist()
coef = logreg.coef_.squeeze().tolist()

# Zip together
labels_coef = list(zip(column_labels, coef))

# Verify the result
print(labels_coef)

Answer 2

zip中的系数和特征

print(list(zip(X_train.columns.tolist(),logreg.coef_[0])))

DataFrame中的系数和特征

pd.DataFrame({"Feature":X_train.columns.tolist(),"Coefficients":logreg.coef_[0]})
