Expression Analysis of Tumors Based on Patterns in Alternative Splicing
summary
Presents an empirical Bayes workflow that models exon inclusion as an overdispersed binomial with empirical Bayes by using Efron’s dispersion trick, showing the MLE of dispersion is approximately gamma so conjugate priors give analytic shrinkage. On simulations the estimator controls FDR versus other methods that report ~10% but actually hit ~40% false discoveries, and on TCGA AML/UVM data proportion‑based clustering finds isoform‑switching signals and plate batch effects and improves sensitivity to shared splicing patterns.
