2 Summary

Gene set analyses have a modular structure, i.e. they consist of

  1. gene level statistics
  2. gene level significance assessment
  3. gene set statistics
  4. gene set significance assessment
  5. statistical conclusion

Alternatively, steps 1.-3. might be replaced by a single global test.

In this paper, 261 different variants of gene set enrichment procedures were evaluated based on simulated and experimental data.

4 Study design and evidence level

4.1 General aspects

  • The simulated data sets have 600 features (genes) and 20 samples (10 vs. 10)
  • The data was simulated with normally distributed noise with variance equals to one
  • 520 genes were consided as uninformative (delta=0, rho=0)
  • Gene sets with different levels of differential expression (delta \in {0, 0.75, 1, -1}) were simulated
  • Gene sets with varying levels of intra-group correlation (rho \in {0, 0.6, -0.6}) were simulated
  • Gene sets that contain regulated and unregulated genes were generated as well as gene set that contain up- and downregulated genes.
