Statistics 1: Introduction to ANOVA, Regression, and Logistic Regression

This introductory course is for SAS software users who perform statistical analyses using SAS/STAT software. The focus is on t tests, ANOVA, and linear regression, and includes a brief introduction to logistic regression. This course (or equivalent knowledge) is a prerequisite to many of the courses in the statistical analysis curriculum.

Learn how to

Generate descriptive statistics and explore data with graphs.
Perform analysis of variance and apply multiple comparison techniques.
Perform linear regression and assess the assumptions.
Use regression model selection techniques to aid in the choice of predictor variables in multiple regression.
Use diagnostic statistics to assess statistical assumptions and identify potential outliers in multiple regression.
Use chi-square statistics to detect associations among categorical variables.
Fit a multiple logistic regression model.
Score new data using developed models.

Predictive Modeling Using Logistic Regression

This course covers predictive modeling using SAS/STAT software with emphasis on the LOGISTIC procedure. This course also discusses selecting variables and interactions, recoding categorical variables based on the smooth weight of evidence, assessing models, treating missing values and using efficiency techniques for massive data sets.
