# Multivariate Statistics for Understanding Complex Data

Course code TPMULT94
Duration 3 Days

• This course teaches how to apply and interpret a variety of multivariate statistical methods to research and business data. Strong emphasis is on understanding the results of the analysis and presenting your conclusions with graphs.

# Prerequisites

• Before attending this course, you should be familiar with statistical concepts such as hypothesis testing, linear models, and collinearity concepts in regression. You should have an understanding of the topics taught in Statistics 2: ANOVA and Regression or equivalent.

Who should attend

• Business analysts, social science researchers, marketers, and statisticians who want to use SAS to make sense of highly dimensional multivariate data

# Delegates will learn how to

• make sense of the math behind many multivariate statistical analyses
• reduce dimensionality with principal components analysis
• identify latent variables with exploratory factor analysis and factor rotation
• understand individual preferences with qualitative preference analysis
• explain associations among many categories with correspondence analysis
• finds patterns of association among different sets of continuous variables with canonical correlation analysis
• explain differences among groups in terms of many predictor variables through canonical discriminant analyses
• classify observations into groups with linear and quadratic discriminant analyses
• fit complex multivariate predictive models with partial least squares regression analysis.
