This course is developed by the Open University, UK, and therefore you will see the course code M346 on the cover and in the course material.

**3.1 Couse units**

The core material for this course is the book *Statistical Modelling Using GENSTAT*, which is written by the Open University, UK. Its contents are as follows.

Chapter 1 Introduction and Review of statistical concepts

Chapter 2 Introduction to GENSTAT

Chapter 3 Linear regression with one explanatory variable

Chapter 4 One-way analysis of variance

Chapter 5 Multiple linear regression

Chapter 6 Analysis of factorial experiments

Chapter 7 Experiments with blocking

Chapter 8 Binary regression

Chapter 9 What are generalized linear models?

Chapter 10 Diagnostic checking

Chapter 11 Loglinear models for contingency tables

Chapter 12 Further data analyses

Each chapter concludes with a brief summary of the main methodological content of the chapter. A final short postscript section, which is not assessed, mentions yet more statistical modelling tools, related to those in the course, but not covered in detail.

The course is based on data and motivated by problems. The book therefore contains many sets of data. A number of examples analyzing these datasets are worked through in the text and lots of exercises for you to do yourself are also provided. The majority of these will require use of your computer.

Each chapter, from Chapters 1 to 12, is timetabled for one to four weeks' study; see the *Presentation Schedule*.

The numbering of examples, exercises, tables and figures each restarts within each chapter: for example, Exercise 4.12 refers to the twelfth exercise in Chapter 4 while Figure 11.3 is the third figure in Chapter 11.

**3.2 Solutions to exercises**

Solutions are provided to all the exercises. Because you will have the opportunity, through the exercises, to work a number of ideas out for yourself, solutions to some of the exercises are quite long and, it is hope, informative!

**3.3 GENSTAT**

GENSTAT is introduced in Chapter 2 of the main course text, with the assistance of the *Genstat Guide*. You need not familiarize yourself with GENSTAT at all before then. GENSTAT will be introduced from scratch, and all students, regardless of statistical computing background (provided you know the basis of Windows), will be on a level playing field. The remainder of the course, from Chapter 2 onwards, will always assume use of GENSTAT and indeed will be explicit about how to use GENSTAT to achieve the necessary ends.

**3.4 Handbook**

A *Handbook* is provided to give you a convenient source of basic definitions and concepts for use throughout the year and during the examination. The *Handbook* entries are slightly expanded versions of the summaries of methodology given at the end of the course chapters. **You will not be allowed to bring the Course Handbook to the exam. Another copy of the handbook will be given to you together with the exam paper.**

**3.5 Broadcasts**

There are no TV or radio programmes associated with this course. Nor is there any recorded audio or video material.

**3.6 Presentation Schedule**

The *Presentation Schedule* sets out an overall schedule for the study weeks for each unit. Assignment cut-off dates and the dates for face-to-face sessions are also incorporated.

Although the suggested study week for each unit is just for your reference, it is important to keep to schedule. For most assignments, the cut-off date is very soon after the end of the study week for the last of the relevant units. We recommend that you try to finish the assignment questions for each unit as soon as you finish the unit, otherwise before the cut-off dates for the assignments you will have a lot of work to do in only a few days.

**3.7 Stop presses**

Stop presses act as a sort of course newsletter, containing useful information of various types. Note that all the stop presses will be posted on the OLE only and no hardcopy will be sent to you. You should always access the OLE for reading stop presses.

**3.8 Errata**

An erratum lists out the mistakes that are in any of the printed course materials. When you read the errata, you should correct the text immediately. Note that all the errata will be posted on the OLE only.
