CAS Exam MAS-I Spring 2019, Question 20

Study guide: Exam MAS-I

A sample of losses has the following observations:

\{400, 600, 900, 1100, 1200\}

A rectangular kernel with bandwidth 300 is used to estimate the probability density function (pdf) of the losses at x = 800. The resulting estimate is \tilde{f}_R(800).

A triangular kernel with bandwidth 300 is used to estimate the pdf of the losses at x = 800. The resulting estimate is \tilde{f}_T(800).

The absolute difference in the estimates is denoted z, where z = \left|\tilde{f}_R(800) - \tilde{f}_T(800)\right|.

Calculate z.

  • A) Less than 0.0001
  • B) At least 0.0001, but less than 0.0002
  • C) At least 0.0002, but less than 0.0003
  • D) At least 0.0003, but less than 0.0004
  • E) At least 0.0004
