Predict next month transactions
You are finally in the stage of predicting next month's transaction with linear regression. Here you will use the input features you've previously built, train the model on them and the target variable, and predict the values on the unseen testing data. In the next exercise you will measure the model performance.
The LinearRegression function from sklearn library has been loaded for you. The training and testing features are loaded as train_X and test_X respectively, and the training and testing target variables are loaded as train_Y and test_Y.
