i need my precision,recall and f1 score results to be like the output below
precision 0.98
recall 0.98
f1 score 0.93
the numbers are just an example
here is my code
#training and test sample :
x1_training_data, x1_test_data, y1_training_data, y1_test_data = train_test_split(x1_data, y1_data, test_size = 0.3)
# Estimation result:
logit_model=sm.Logit(y1_training_data,x1_training_data)
result1=logit_model.fit()
print(result1.summary2())
# Model Evaluation:
logreg=LogisticRegression()
logreg.fit(x1_training_data,y1_training_data)
y1_pred=logreg.predict(x1_test_data)
print('Logistic regression model accuracy:{:.2f}'.format(logreg.score(x1_test_data,y1_test_data)))
print("Logistic Regression F1 Score :",f1_score(y1_test_data,logreg.predict(x1_test_data),average=None))
here is my results of the code
logistic Regression Accuracy after undersampling : 0.902297169964584
Logistic Regression F1 Score after undersampling : [0.90023556 0.9042753 ]
i had two numbers for the F1 score i wanted to be just one number and i do not know how and i tried to find a code to find out the precision or the recall and i could not find any
please help me at least with the F1 score output Thank you
From sklearn import the metrics
from sklearn.metrics import f1_score
from sklearn.metrics import precision_score
from sklearn.metrics import recall_score
Split data and train the model
#training and test sample :
x1_training_data, x1_test_data, y1_training_data, y1_test_data = train_test_split(x1_data, y1_data, test_size = 0.3)
# Estimation result:
logit_model=sm.Logit(y1_training_data,x1_training_data)
result1=logit_model.fit()
print(result1.summary2())
# Model Evaluation:
logreg=LogisticRegression()
logreg.fit(x1_training_data,y1_training_data)
y1_pred=logreg.predict(x1_test_data)
Print the metrics, here for the average parameter you can change it check sklearn for details
print('precision: %.2f' % precision_score(y1_data, y1_pred,average='weighted'))
print('recall: %.2f' % recall_score(y1_data, y1_pred,average='weighted'))
print('f1_score: %.2f' % f1_score(y1_data, y1_pred,average='weighted'))
