Course Outline:
The sequence of Stat 325/425-326/426 introduces classical and modern applied statistics. It is designed for students who have some knowledge of statistics but are still not clear what to do when confronted with data. Stat 325/425, the first part of the sequence, covers basic exploratory data analysis for univariate (response) observations with or without single or multiple covariates. Graphical methods and data summarization are followed by model-fitting using R/S-plus computing language (read a news report on R from New York Times). Topics include simple and multiple regression, transformation, model selection, diagnostics, robust procedures, ANOVA and analysis of covariance and interpretation of results. Some non-traditional approaches and biases in sampling and data analysis will be discussed at the end of semester (time permitting). Lectures include case studies, computer demonstration and group discussion.
Prerequisite: Matrix algebra such as Math 201, and some basic statistics class such as STAT207/208, or STAT 244 (that covers estimation and hypothesis tests), or STAT 312, or Stat 346, or one of EPBI 431/481.
