Question 1

+2 marksOne correct option
  1. A

    We consider these values as i.i.d U (0, 1) because the histogram shows an almost perfect uniform distribution.

  2. B

    The trace plot shows that the generated random values are not independent.

  3. C

    The trace plot shows that the generated random values are independent.

  4. D

    We consider these values as i.i.d. U (0, 1) because the trace plot shows a random pattern.

Based on the above data, answer the given subquestions.

Find the probability of acceptance for U[0, 2] as a proposal distribution. Enter the answer correct to two decimal places.

Show answer

Correct answer: 0.33 (accepted within ±0.03)

Question 6

+2 marksNumerical answer

Based on the above data, answer the given subquestions.

Find the expected number of loops for an acceptance when U[0, 1] is considered as a proposal distribution. Enter the answer correct to one decimal place.

Show answer

Correct answer: 1.5

Question 7

+2 marksOne correct option

Based on the above data, answer the given subquestions.

Which proposal distribution would be a better choice?

  1. A

    U [0, 1] is better since it gives a larger value of c than U [0, 2].

  2. B

    U [0, 2] is better since it gives a smaller value of c than U [0, 1].

  3. C

    U [0, 1] is better since it gives a smaller value of c than U [0, 2].

  4. D

    Both proposal distributions are equally effective.

Show answer

Correct answer

  • C

    U [0, 1] is better since it gives a smaller value of c than U [0, 2].
