Statistics 2 coursework bivariate data

This model can be applied to nominal data. This model can only be applied to ordinal data, since modelling the probabilities of shifts from one category to the next category implies that an ordering of those categories exists.

The proportional odds model has a very different structure to the other three models, and also a different underlying meaning. There are variants of all the models that use different link functions, such as the probit link or the complementary log-log link. Ordinal data can be visualized in several different ways. Common visualizations are the bar chart or a pie chart. Tables can also be useful for displaying ordinal data and frequencies. Mosaic plots can be used to show the relationship between an ordinal variable and a nominal or ordinal variable. Color or grayscale gradation can be used to represent the ordered nature of the data.

A single-direction scale, such as income ranges, can be represented with a bar chart where increasing or decreasing saturation or lightness of a single color indicates higher or lower income. The ordinal distribution of a variable measured on a dual-direction scale, such as a Likert scale, could also be illustrated with color in a stacked bar chart.

A neutral color white or gray might be used for the middle zero or neutral point with contrasting colors used in the opposing directions from the midpoint, where increasing saturation or darkness of the colors could indicate categories at increasing distance from the midpoint. The use of ordinal data can be found in most areas of research where categorical data are generated. Settings where ordinal data are often collected include the social and behavioral sciences and governmental and business settings where measurements are collected from persons by observation, testing, or questionnaires.

Some common contexts for the collection of ordinal data include survey research ; [16] [17] and intelligence , aptitude , and personality testing. From Wikipedia, the free encyclopedia. Not to be confused with Ordinal data programming.

Marsden, Peter V. Assessing the Reliability and Validity of Survey Measures. Handbook of Survey Research. It is aimed at students who enjoy maths and are interested in probability and statistics.

M.S. Program in Statistics | UC Davis Department of Statistics

It is useful for students with interests in Econometrics, Operations Research, Finance, and theoretical aspects of Marketing Research, as well as those who have Maths or Statistics as their main interest. Topics studied include : Probability, discrete and continuous distributions, likelihood and estimation, hypothesis testing. This course introduces a variety of computer technologies relevant to storing, managing, and processing data. The course has two aims: to teach software tools specific to the handling of data, and to teach and build confidence with general concepts of computer languages.

It is useful for students with interests in applying statistics in business or research environments. Lectures will be reinforced with weekly lab work.

Topics studied include : How to write computer code; publishing data on the World Wide Web HTML ; data description and semantic markup XML ; data storage file formats, spreadsheets, databases ; data management and summary database queries, SQL ; R programming and data manipulation. STATS considers a range of practical operations research problems, including effective use of limited or valuable resources such as machines and personnel, understanding queues and simulation. The course is valuable for students interested in Commerce, Statistics, Mathematics, and Computer Science. STATS will emphasise the relationship between business and industrial applications and their associated Operations Research models.

Graduate Certificate in Theory & Applications of Regression Models

Computer packages will be used to solve practical problems. Topics such as: linear programming, transportation and assignment models, network algorithms, queues, inventory models, simulation, analytics and visualisation will be considered. This book can be purchased from the Student Resource Centre when in stock. SAS is a major commercial statistics package that is used at about 40, sites worldwide, and by four million users. To date all the data you have seen has usually been given to you in a form ready for exploration and modelling. This is rarely the case in most day-to-day projects in industry.

For further details refer Cecil Notice or talk to your professor. For advice: Mike Forster ext This course covers the exploratory analysis of multivariate data, with emphasis on the use of statistical software and reporting of results. Software-based exploration of multivariate data. Modern extensions to high dimensional and non-normal data.

STATS 701 Advanced SAS Programming

Topics studied include : Visualisation, Principle components, factor analysis, ordination, cluster analysis, multivariate multiple regression and associated methods. The approach will be largely non-mathematical and practical, with an emphasis on the understanding of the techniques. Available from the University Bookshop. This course follows on from course STATS and provides the theory underlying the statistical methods used in other courses.

Many BSc Hons Statistics courses use this course as a prerequisite. It is a good course for students with interests in mathematics, econometrics or finance, as well as those who consider their main interest to be statistics. This course concentrates on stochastic methods used in operations research, biology etc. It covers the construction, analysis and simulation of stochastic models, as well as some optimisation questions connected with these models. Topics studied include : The Poisson process, birth and death processes, queueing theory, simulation, random number generation, variance reduction, and optimisation.

This course looks at the theory of stochastic processes, showing how complex systems can be built up from sequences of elementary random choices. The approach will be largely non-mathematical and practical, with an emphasis on applications using R and an appreciation of the problems associated with modelling time series data. These extensions permit, for example, the building of models for response variables which are not continuous. The main statistical computer package used is R. It is also a useful complement to Computer Science. Topics studied include : Application of the generalised linear model to fit data arising from a wide range of sources, including multiple linear regression models, log-linear models and logistic regression models.
