Wikipedia is a fantastic project. I've been working on these pages:
Ballet/Karate:
- Ulyana Lopatkina (reorganization, new and improved information, major editing)
- Galina Mezentseva (page creation)
- Japan Karate Association (major reorganization)
Math/Statistics:
- Mean Squared Error (corrections on the MSE expressions and technical comments)
- F distribution (editing and addition of properties)
- Chi-square distribution (references and properties)
- Laplace's method (major reorganization, spliting from steepest descents)
- Watson's lemma (page creation)
- Faà di Bruno's formula (credited the first statement to Arbogast, in 1800)
- Proofs of convergence of random variables (corrections made on proofs)
Biographical notes on mathematicians/statisticians:
- G.N. Watson (added that he proved in 1918 what is known as Watson's lemma)
- Louis François Antoine Arbogast (mentioned that he was the first to state Faà di Bruno's formula)
- Francesco Faà di Bruno (mentioned that his role in developing the formula is controversial)
Its a minor contribution but has been fun.
- See this link to find out the number of accesses to an wikipedia article.
My interests (professional and for fun):
- Statistics and probability theory
- Operations research (optimization, decision analysis)
- Computer science and IT
- Economics and Business applications
- R Project
- Ballet (my daughter is a ballerina! and I like to watch)
- Karate (I've practiced with some interruptions for the last 30 years - Shotokan, JKA)
My academic background includes a Ph.D. at Stanford University and I work as a faculty at a major university in Brazil.
Suggestions and comments are welcomed.
