This course aims to develop your understanding of the statistical concepts of parameter estimation and hypothesis testing that are fundamental for real life applications of statistics as well as for numerous further courses in the curriculum of the statistics track.

Upon successfully completing this course, you should be able to:

- Apply basic probability concepts such as PMF, PDF, CDF, expected values, variance, and moments in a statistical context and perform the involved computations of series and integrals.
- Use standard probability distributions to model statistical scenarios and to derive useful conclusions from computations based on these distributions.
- Explain the relevance of the Central Limit Theorem for statistics.
- Construct parameter estimators using the maximum likelihood method and the method of moments.
- Rigorously assess the quality of parameter estimators.
- Analyse the asymptotic properties of parameter estimators.
- Construct exact and approximate confidence intervals.
- Explain the purpose and philosophy of hypothesis testing, as well as the meaning of p-values.
- Given a dataset, create and apply a useful hypothesis test based on these data.
- Compute the size and power of a hypothesis test.
- Construct most powerful tests using the Neyman-Pearson Lemma.

These are the relevant SPMS-MAS Graduate Attributes.

## 1. Competence

a. Independently process and interpret mathematical theories and methodologies, and apply them to solve problems

b. Formulate mathematical statements precisely using rigorous mathematical language

c. Discover patterns by abstraction from examples

## 2. Creativity

c. Develop new applications of existing techniques

## 3. Communication

a. Present mathematics ideas logically and coherently at the appropriate level for the intended audience

Midterm exam: Feedback on common mistakes and the level of difficulty of the problems is given.

Assignment: Students will receive individual feedback on their performance in the assignments during the tutorial sessions.

Lectures (39 hours) | The lectures cover the basic theory of parametric statistics using the following approach: - Illustration of concepts and theorems by numerous examples |

Tutorials (12 hours) | Two types of tutorial problems will be given: 1) Problems that test comprehension of basic definitions and theorems. 2) More advanced problems that either require quite strong computational and reasoning skills or creativity in coming up with mathematical proofs. |

Absence Due to Medical or Other Reasons

If you are sick and not able to attend a quiz or midterm, you have to submit the original Medical Certificate (or another relevant document) to the administration to obtain official leave. In this case, the missed assessment component will not be counted towards the final grade. There are no make-up quizzes or make-up midterm.

Good academic work depends on honesty and ethical behaviour. The quality of your work as a student relies on adhering to the principles of academic integrity and to the NTU Honour Code, a set of values shared by the whole university community. Truth, Trust and Justice are at the core of NTUâ€™s shared values.

As a student, it is important that you recognize your responsibilities in understanding and applying the principles of academic integrity in all the work you do at NTU. Not knowing what is involved in maintaining academic integrity does not excuse academic dishonesty. You need to actively equip yourself with strategies to avoid all forms of academic dishonesty, including plagiarism, academic fraud, collusion and cheating. If you are uncertain of the definitions of any of these terms, you should go to the Academic Integrity website for more information. Consult your instructor(s) if you need any clarification about the requirements of academic integrity in the course.
