Join Predicted values with test dataset

[bhuwan]

By doing above concat, does each row of y_test and y_pred align in the same order as in x_test?

The .predict doesn't change the order of classified cases. Let X_test.shape = (m, n), then
y_test.shape = n (preserving order is guaranteed by train_test_split in this case); finally, y_pred is produced by .predict, this function retains the order of classified items (rows of X_test).

Thank you so much, this is what I needed to confirm.
