Resampling methods for variance estimation of singular value decomposition analyses from microarray experiments



The R code for implementing the methods in the paper can be downloaded here . Note in the documentation that the software requires both the mva and mclust libraries, which can be downloaded from here.



Analysis of Data from Cho et al. (2001, Nature Genetics):


Plots of variance for indidividual principal components for experiments N2 and N3 .

Plots of characteristic modes for experiment N2:
  • Characteristic modes 1-4
  • Characteristic modes 5-8
  • Characteristic modes 9-11


    Plots of characteristic modes for experiment N3:
  • Characteristic modes 1-4
  • Characteristic modes 5-8
  • Characteristic modes 9-11


    Plots of characteristic modes and associated 99% confidence intervals for experiment N2 with replicate data (resampling columns):
  • Characteristic modes 1-4
  • Characteristic modes 5-8
  • Characteristic modes 9-11


    Plots of characteristic modes and associated 99% confidence intervals for experiment N2 with replicate data (resampling rows):
  • Characteristic modes 1-4
  • Characteristic modes 5-8
  • Characteristic modes 9-11


    Plots of characteristic modes and associated 99% confidence intervals for experiment N2 without replicate data (resampling columns):
  • Characteristic modes 1-4
  • Characteristic modes 5-8
  • Characteristic modes 9-11
