Question 24

+3 marksOne correct option

Consider the following code:

python
import numpy as np
from sklearn.linear_model import LinearRegression
X = np.array([[1, 1], [1, 2], [2, 2], [2, 3], [2, 1], [3, 3]])
# y = 1 * x_0 + 2 * x_1 + 3
y = np.dot(X, np.array([1, 2])) + 3


reg1 = LinearRegression(fit_intercept = False).fit(X, y)
s1 = reg1.score(X, y)


reg2 = LinearRegression(fit_intercept = True).fit(X, y)
s2 = reg2.score(X, y)

Which of the following is more likely to be true?

  1. A

    s1 = s2

  2. B

    s1 < s2

  3. C

    s1 > s2
