To write a python program to implement multivariate linear regression and predict the output.
- Hardware – PCs
- Anaconda – Python 3.7 Installation / Moodle-Code Runner
Import pandas as pd.
Read the csv file.
Get the value of X and y variables.
Create the linear regression model and fit.
Predict the CO2 emission of a car where the weight is 2300kg, and the volume is 1300cm3.
Print the predicted output.
import pandas as pd
from sklearn import linear_model
df = pd.read_csv("cars.csv")
X = df[['Weight', 'Volume']]
y = df['CO2']
regr = linear_model.LinearRegression()
regr.fit(X, y)
print('Coefficients:', regr.coef_)
print('Intercept:',regr.intercept_)
predictedCO2 = regr.predict([[3300, 1300]])
print('Predicted CO2 for the corresponding weight and volume',predictedCO2)
Thus the multivariate linear regression is implemented and predicted the output using python program.
