Do you like to learn the statistical tools
required for the analysis of microarray data, how to apply them using R
software and how to interpret the results meaningfully. We will review the
biology relevant to microarray data, then cover microarray experiment set up,
quantification of information generated from the experiment, pre-processing of
data including statistical tools for between array and within array
normalization, statistical inference procedures to identify differentially
expressed genes under two different conditions, and its extension to situations
involving more than two conditions. The course will also introduce multivariate
statistical methods, such as principal component analysis & cluster
analysis. These methods help to identify differentially expressed genes, sets
of co-regulated genes, which in turn will help to assign functions to genes. An
appendix is provided which will introduce the bioconductor packages and their
use in the analysis of Affy data and two commonly used designs viz. Dye swap
and Reference.

Who Should Take This Course:
Biologists and geneticists who need to use
statistical methods to analyze microarray data; also computer scientists and
statisticians involved in microarray analysis projects. The course is designed
to bridge the gap between several disciplines by providing the necessary
information to participants with varied background.
Course Program:
Course outline: The course is structured as follows

- Concordance coefficients and their use in
normalization.
- Numerical illustration for 4-6 with complete
set of annotated R-commands.
- Instructions for the use of Bioconductor
SESSION
2: Statistical Inference Procedures in Comparative Experiments
- Basics of statistical hypothesis testing.
- Two sample t- test.
- paired t-test.
- Tests for validating assumptions of t-test.
- Welch test.

- Adjustments for Multiple hypotheses testing
including false discovery rate.
- Numerical illustration for 2-8 with complete
set of annotated R-commands.
- One way ANOVA.
SESSION
3: Multivariate Techniques
- Principal component analysis.
SESSION
4: Clustering
- Cluster analysis.
The instructor, Dr.
Sudha Purohit is visiting Lecturer in Statistics at the University of Pune and,
before her retirement in 2000, was Head of the Department of Statistics at A.
G. College, Pune, India. Her areas of interest are survival analysis,
reliability, programming with R and analysis of microarray data. She has
published a number of research papers in various peer-reviewed journals.
You will be able
to ask questions and exchange comments with Dr. Sudha Purohit via a private
discussion board throughout the course. The courses take place
online at statistics.com in a series of 4 weekly lessons and assignments, and
require about 15 hours/week. Participate at your own convenience; there
are no set times when you must be online. You have the flexibility to work a
bit every day, if that is your preference, or concentrate your work in just a
couple of days.
For Indian
participants statistics.com accepts registration for its courses at special
prices in Indian Rupees through its partner, the Center for eLearning and
Training (C-eLT), Pune.
