SM512 ทฤษฎีสถิติ

(Statistical Theory)

ปีการศึกษา 2564

วิชานี้นำเสนอทฤษฎีและหลักการทางสถิติและความน่าจะเป็นที่จำเป็นสำหรับการวิเคราะห์ทางวิศวกรรมการเงิน โดยเริ่มจากหลักการพื้นฐานของทฤษฎีความน่าจะเป็น (probability theory) ความน่าจะเป็นแบบมีเงื่อนไข (conditional probability) ตัวแปรสุ่มและการแจกแจง (random variables and their distributions) ค่าคาดหมายและโมเมนต์ของตัวแปรสุ่ม (expectation and moments) คุณสมบัติและรูปแบบของการแจกแจงที่ได้รับความนิยมเป็นพิเศษ (special distributions) ทฤษฎีบทสำคัญในทางสถิติ 1) Law of Large Number 2) Central Limit Theorem ซึ่งจะบ่งบอกถึงคุณสมบัติของค่าเฉลี่ยเมื่อกลุ่มตัวอย่างมีขนาดใหญ่มาก การประมาณค่าพารามิเตอร์ด้วยวิธีแบบ maximum likelihood estimation และ Bayes estimation การแจกแจงของตัวประมาณค่า (sampling distributions of estimators) หลักการของการทดสอบสมมุติฐาน (hypothesis testing) และอาจรวมถึงแบบจำลองทางสถิติแบบเชิงเส้น (linear statistical models) วิธีการประมาณค่าแบบ nonparametric

1. Course Objective

The aim of this course is to give master-level students an introduction to principles, theories, and tools in advanced statistical theory. Students will also learn how to apply statistical models with real data using STATA software.

3. Required Textbooks:

1. DeGroot, Morris H. and Mark J. Schervish. 2012. Probability and Statistics. 4th edition: Preason. [DS]

2. Hogg, Robert V., Allen T. Craig and Joseph W. McKean. 2005. Introduction to Mathematical Statistics. 6th edition, Pearson. [HCM]

Optional Textbooks:

  1. Ross, S. M. (2014). Introduction to Probability Models. Academic press.

4. Grades and Requirements

Grades will be based on the following weights:

30% Assignment(s)

30% Mid-Term Exam

40% Final Exam

Tentative Grading Range:

85 – 100 A

80 – 84 B+

70 – 79 B

65 – 69 C+

55 – 64 C

50 – 54 D+

40 – 49 D

39 or less F

4.1. Assignment

Students will be assigned to complete 12-15 individual assignments during the semester. An assignment with the lowest score will be dropped when calculating the total score for each student. Note: Late submission of the assignments is not accepted; a score of zero will be recorded for such assignment.

4.2. Examination

There will be two examinations: a mid-term exam counting for 30% of the total points, and a final exam counting for 40% of the total points. If a student misses a regular examination without acceptable excuse, a score of zero will be recorded for the examination.
