Welcome to Keiji's Wiki pages! This wiki is (for now) mainly used to:

• Manage research projects that I'm involved
• Keep track of ongoing analysis
• Provide a convenient way to share analytic results with collaborators and clients

In the future, I may be using this wiki to keep my notes on various statistical topics!

Restricted access: Only authorized users can view contents in each project. Projects are sorted in alphabetical order:

• Anthocyanin study
• BESO study
• Cervical cancer screening
• Colorectal cancer screening
• Choice of medical care
• Dementia incidence by Medicare
• Egg & cognitive function
• Medicare AHS-2 study
• Statistical analysis of DNA methylation
• VB12 biomarkers
• WAHA misc analysis
• WAHA omega-3
• WAHA VB12 biomarkers
• Walnut-body weight study

But I'm so lazy and I just post links here:

• Data dredging (Wikipedia)
  • "This is done by performing many statistical tests on the data and only paying attention to those that come back with significant results…"
• Remember: p-values Are Not Effect Sizes (Win-Vector Blog)
• When differences in significance aren’t significant differences (Statistics Done Wrong)
  • Or maybe read the original paper by Gelman & Stern, 2006 (link to PDF).
• The Abuse of Power: The Pervasive Fallacy of Power Calculations for Data Analysis by Hoenig & Heisey, 2001 (American Statistician)
  • Its PDF is available at the author's website
• Dynamite plots must die (Simply Statistics)
  • Let's kill them all.
• Don’t go 3D (Fundamentals of Data Visualization)
  • "[3D plots] are also almost always inappropriately used." Again, let's kill them all.

• Why do I use Wiki for research?
