MATH5846 Introduction to Probability and Stochastic Processes Semester 1, 2014 CRICOS Provider No: 00098G MATH5846 – Course Outline Course Authority and lecturer: Dr Diana Combe Email: [email protected] Phone: 9385 7022 Office: RC-1032. Consultation: Consultation times are by appointment. Please speak to the lecturer in class, or send an email, to arrange a time. Credit, Prerequisites, Exclusions: This course counts for 6 Units of Credit (6UOC). There are no prerequisites or exclusions for this course. Lectures: The lectures run in weeks 2-7 of the UNSW Semester 1, 2014. That is, they start on Tuesday 11th March and finish on Thursday 17th April. The class meets twice a week for three hours. In each 3 hour class meeting there will be a couple of hours of lectures, a tutorial time and a short break. Tuesday 5-8 pm QUAD–G040 Thursday 5-8 pm QUAD–G048 Course Overview Probabilistic concepts are necessary to study various complex phenomena arising in Engineering, Biology, Medicine and Economics. In this course we introduce basic concepts which are needed to analyze such phenomena. In particular, we discuss the concepts of random events, random variables, structures of dependence, computation of probabilities using the Central Limit Theorem, simple Markov chains and Brownian motion. We may look at Poisson processes if time allows. Assessment Assessment in this course will consist of three assignments (10% each), a class test (20%), and a final examination (50%). Assessment criteria: For each assessment task, the main marking criteria will be clear and logical presentation of correct solutions. Assignments: There are three (written) assignments. These assignments are due in at the start of the classes on each of Tuesday 25th March, Tuesday 1st April and Thursday 17th April. Late assignments will not be accepted. Each assignment will be available at least 10 days before it is due to be submitted. Weighting: Each of the three assignments has a 10% weighting in your final mark. Assignments give an opportunity for students to receive feedback on their progress during the course, and to try their hand at more difficult problems requiring more than one line of argument. Assignments also give an opportunity to introduce aspects of the subject which are not explicitly covered in lectures. Assignments must be YOUR OWN WORK, or severe penalties will be incurred. 2 Class Test: Duration: 1 hours duration, held during class, 5pm, Tuesday 8th April. The test will be held at the start of the class time. A mid-session test gives an opportunity for students to demonstrate their understanding of the first part of the course, and to receive feedback on the presentation of their solutions in under examination conditions. The class test will assess material from chapters 1 - 6. Further detail concerning the mid-session test will be made available in lectures and on the MATH5846 web page, closer to the time. Weighting: 20% of your final mark. Final Examination: Duration: 2 hours duration, held on Thursday 24th April at 5pm to be held in the Red Centre, level 4, RC-4082 Rationale: The final examination will assess student mastery of the the whole course. Weighting: 50% of your final mark. Further details about the final examination will be available in class closer to the time. Announcements will also be made on the MATH5846 web page. Every class is different, and to accommodate this, some variation from the above assessment schedule may be prudent. Hence the above schedule should be considered as a guide only, as it may possibly not be strictly adhered to. In the case of assessment dates, no changes will be made without consultation with the class as well as confirmation being posted as an announcement on the course web page. 3 Schedule of assessment tasks and lecture chapters Week beginning Lecture chapters 10th March chapters 1 and 2 17th March chapters 3 and 4 24th March chapters 4 (cont) and 5 31st March chapter 6 7th April chapter 7 14th April chapter 8 21st April no lectures this week Assessment due Assessment weighting Assignment 1 due at class 10% 5pm Tuesday 25th March Assignment 2 due at class 10% 5pm Tuesday 1st April 1 hour class test 20% 5 pm Tuesday 8th April Assignment 3 due at class 10% 5pm Thursday 17th April 2 hour final exam 50% 5pm Thursday 24th April held in RC-4082 It is intended that the following topics will be covered in the given order. Sometimes the particular chapters will not fit exactly into a particular week. Chapter 1 – Probability: Experiments, axioms and basic results, conditional probability, independence, Bayes’ Formula. Chapter 2 – Random Variables: Definition, cumulative distribution function, discrete and continuous random variables, expectations, moments, standard deviation, moment generating functions, Chebychev’s Inequality. Chapter 3 – Common Distributions: Bernoulli, Binomial, Poisson, Geometric, Hypergeometric, Uniform, Normal, Exponential, Gamma and Beta distributions. Chapter 4 – Bivariate Distributions: Joint cdf, probability function and density function, conditional probability and density functions, conditional expected value and variance, covariance and correlation, the bivariate normal distribution, extension to n random variables. Chapter 5 – Transformations: Linear transformations, probability integral transformations, bivariate transformations, sums of independent random variables. Chapter 6 – Convergence of Random Variables: Convergence in probability, weak law of large numbers, Central Limit Theorem, applications. Chapter 7 – Markov chains. Chapter 8 – Brownian motion. 4 Additional resources and support Exercises: Sets of exercises will be given out, and made available on the course web page. These problems are for you to do to enhance mastery of the course. Some of the problems will be done in lectures, but you will learn a lot more if you try some of them beforehand. Textbooks: Although there is no set text for this course, the following references may prove useful. These books are available from the UNSW library, and are all available from the main shelves as well as available for from the ‘High Use Collection’.

To log in to Moodle use your zID and zPass at the following URL: http://moodle.telt.unsw.edu.au All course materials, including lecture notes, will be available on the MATH5846 homepage. You should check regularly for new materials. Course Evaluation and Development The School of Mathematics and Statistics evaluates each course each time it is run. We carefully consider the student responses and their implications for course development. It is common practice to discuss informally with students how the course and their mastery of it are progressing.
