Title: multtest: Resamplingbased Multiple Testing Procedures


1
multtest Resampling-based Multiple Testing
Procedures
  • Test Statistics T, F (one and two factor),
    linear and coxph regression, plus non-parametric
    analogs of each.
  • Type I error rates FWER, FDR, gFWER and TPPFP.
  • Null Distribution Estimators permutation and
    bootstrap.
  • MTP object a new class for multiple testing
    results from MTP function
  • Slots test statistics, estimates, sample size,
    rawp, adjp, cut-off vector, confidence intervals,
    rejection decisions, null distribution, call,
    seed.
  • Methods print, summary, plot, as.list, subset.

hopach Hierarchal Clustering w/ Bootstrap
Visualization
  • Hybrid of partitioning and agglomerative
    clustering methods
  • Main clusters (labels, medoids, ordering within
    clusters),
  • Hierarchical tree (ordering in the final level).
  • Uses Median Split Silhouette (MSS) to automate
  • 1. Number of child clusters at each internal node
    (not binary),
  • 2. Decision to collapse two nodes (not
    necessarily siblings),
  • 3. Stopping rule to identify the main clusters.
  • Distance Metrics Euclidean, correlation,
    cosine-angle, abs value of these.
