Introduction to Nonparametric Statistics

Description

Nonparametric analogs of the one- and two-sample t-tests and analysis of variance; the sign test, median test, Wilcoxon’s tests, and the Kruskal-Wallis and Friedman tests, tests of independence. Nonparametric regression and nonparametric density estimation, modern nonparametric techniques, nonparametric confidence interval estimates.

Midterm Project Content

Some optional guidelines:

  1. State the problem
  2. Describe the data
  3. Review what statistical methods are available to analyze your data
  4. List their advantages and disadvantages, in particular compare nonparametric to parameteric methods
  5. Propose a solution using nonparametric methods
  6. List all the tasks that you plan to do: collecting data, programming, simulating data, estimating, testing, etc.
