A Non-parametric Approach for Testing the Similarity of Ganglioside Profiles
September 12, 2007 106 AH
Abstract
In Statistics, it is often of interest to compare means from two or more
populations. This is usually carried out by the method called Analysis of Variance
(ANOVA). However, the comparison becomes complicated when the data to analyze is assumed
to have a functional form. In this talk, we introduce a test analogous to the classical
ANOVA which is based on a distribution-free procedure to compare similarity between sets
of curves. We employ the constructed test statistic on a study comparing ganglioside
profiles (complex brain proteins) in rats. We provide the asymptotic distribution of the
proposed test statistic and validate these results with a small simulation study.
