Student Project Idea 6

Data Imputation with cDNA Microarray Data

Microarry techniques allow us to monitor the expression level for thousands of genes at once. The data from these experiments often includes a substantial amount of missing data due to technical error. The missing data creates issues for various statistical analyses, therefore some researchers implement various strategies of "data imputation" in order to fill in the missing data. Most of the comparative evaluation of these strategies has been done with very large data sets from cancer research or model organisms. In my lab our data sets are of a more modest size due to the limitations on samle collection. What is the affect of data imputation, and what is the most effective strategy for these data sets?


This project, or others involving the devopment of statistical analyses for microarray data would be conducted in collaboration with Albyn Jones of the Math Department.
