Web Services for Tasks Associated with Statistical Analyses

These resources go beyond statistical calculators, but do not require computational skills.


u-Statistics for multivariate ordinal data (grid powered Web server, muNews RSS feed, discuss)
Knut M. Wittkowski, The Rockefeller University, Email;
maintained by: Tingting Song, Email
Reference: Nonparametric methods for molecular biology (Wittkowski 2010)
(based on muStat package for multivariate ordinal data, see R Packages)

  • scoring complex phenotypes (including recurrent, graded, and censored adverse events with varying attribution (Morales (2008))
  • screening microarrays for gene expression profiles (sets of collaborating genes)
  • screening whole genome scans for epistasis between multipoint ranges (diplotypes)
  • sorting hierarchical genotype/expression/phenotype factor structures by information content
  • developing metrics for biostatistical and epidemiological collaborations (Rubio 2011)


Web-based Interactive Study Design, Organization, and Management (discuss)

WISDOM provides a GUI and a layered study meta data ontology for:
  • importing study meta data from previous studies and standardized outcomes ontologies,
  • automatically creating an Oracle data base
  • exporting CRF definitions (data dictionaries) into REDCap (Vanderbilt) and Epi Info™ (CDC)
  • copying and pasting data between spreadsheets (MS Excel, OO Calc ...) and statistical programs (SPSS, SAS ...) and a Web-accessible and secure ORACLE data base for sharing with collaborators.
  • importing data from various sources (in progress)
  • assisting analyses with ΅Stat , R, SAS, ... (in progress)
  • setting up interim analyses to report study progress and emerging risks (planned)
  • automatically producing analyses for primary objectives (planned)
  • conducting bootstrapped power calculations (planned)
  • facilitating data sharing by adding study design information (in progress).
