Small-world network

Small-world networks have shown up recently in lots of literature. It's an interesting mathematical topic, but also something that is readily understood by non-mathmaticians. A good graphic, example, some better history on the subject, and some rewriting could make this a featured article.

2. Debivort 21:45, 5 January 2006 (UTC) This is a topic dear to my heart, and I would help push it up to Featured quality.
3. Rohit_math 01:03, 7 Jan 2006 (IST) I might choose a topic i like the next time, this week i go with Debivort! ;-).

5. stochata 14:12, 14 January 2006 (UTC) I started the article, and I'd be first in line to say yes to the suggested list of improvements. I promise I'll help out elsewhere!

Comments:

• Needs to be written; could be a great article if made COTW. ral315 17:14, Feb 10, 2005 (UTC)
• Such an article should link to: Archimedes, Euclid, Thomas Heath, Archimedes Palimpsest, how Archimedes used infinitesimals, stereographic projection, Hipparchus, Euclidean algorithm. Michael Hardy 21:21, 11 Feb 2005 (UTC)
• I would really love to see this article written, but this is a very broad topic — Britannica devotes ~8,000 words to Greek mathematics in its "history of mathematics" article alone. Perhaps something a bit less ambitious might be more prudent for a first go. Paul August ☎ 22:56, Feb 11, 2005 (UTC)

• Again, a great subject and one that could become featured.
• Good subject, especially since the basic concept is comprehensible to someone off the street. The crypto folks should be helpful on this one. Isomorphic 18:00, 11 Feb 2005 (UTC)
• See the article on shuffle for some mathematical detail about shuffling algorithms. -- The Anome 19:29, Feb 11, 2005 (UTC)
• This topics intersects both probability theory and combinatorics. The number of fixed points of a random bijection of {1, ..., n} is equal to zero with a probability that can best be calculated by a very elegant application of the inclusion-exclusion principle. Its probability distribution approaches a Poisson distribution as n grows. Its first n moments are exactly those of the Poisson distribution. Uniform distribution of random permutations often occurs as a null hypothesis in statistical inference. Michael Hardy 21:19, 11 Feb 2005 (UTC)

Tensor

Nominated February 11, 2005

3. The Anome 19:16, Feb 11, 2005 (UTC)

Comments:

• Currently unusable, yet about a key concept in modern mathematics. Just about gets over the idea of scalar -> vector -> matrix -> tensor, but does not answer newbie questions such as "are all matrices tensors?" or "does being a tensor constrain the values in the array?", and yet does not do a proper abstract treatment either or mention pseudotensors or dual spaces. We need an article which is accessible both to K-12 students and mathematicians. -- The Anome 04:07, Feb 11, 2005 (UTC)
  • Do you support it, then, The Anome? I noticed you didn't sign it, YOU ARE ALLOWED TO SIGN YOUR OWN ARTICLE. ral315 05:03, Feb 11, 2005 (UTC)
  • Much of the problem with the article comes down to this: there are many people (perhaps a majority of those with an interest) who are much better at saying how tensors should be taught, than what they are (not the same thing, in this case). Wading in to change the article around may not help. Whether an array is a tensor is not a question that can be answered in very naive terms. I'd suggest chipping away at the problem, first. Could we have tensor density? If that were clearly written, we could write tensor excluding tensor densities, which excludes one complication. Charles Matthews 15:33, 11 Feb 2005 (UTC)
    • As I don't know much about tensors myself, it's something I'd have to look at. However, we could split the article into Tensors and Tensor Densities- it doesn't sound bad to me. ral315 15:50, Feb 11, 2005 (UTC)

Manifold: 20 July 2005

I nominate manifold. It is in the process of going through a rewrite and being split up as well. Help wanted. I think we can have this up to featured in a couple of weeks.--MarSch 28 June 2005 12:13 (UTC)

2. This article has already seen many edits and generated a lot of discussion, but is still not in good shape. Manifold is a central topic in mathematics with applications in physics and computer graphics, so this could become a great article. -- Jitse Niesen (talk) 3 July 2005 02:44 (UTC)

• non-existant article, about a basic math tool. Falphin 01:37, 24 Jun 2005 (UTC)
• Surely you mean Calculator, no?--Pharos 05:13, 24 Jun 2005 (UTC)
  • Sorry, Yes I was in a hury to find an article and didn't check my spelling. LoL. Falphin 12:49, 24 Jun 2005 (UTC)
  • I still nominate it because it lacks a history section.--Zxcvbnm 17:01, 25 Jun 2005 (UTC)
    • Umm... no it doesn't. See Calculator#History.--Pharos 17:05, 25 Jun 2005 (UTC)
      • Well thats because i added one. --Zxcvbnm 00:32, 27 Jun 2005 (UTC)
        • Ahh, never mind.
      • Ah, you'll have to forgive my absent-mindedness; you did a pretty good job on that section too.--Pharos 02:19, 27 Jun 2005 (UTC)

• This article is long enough to be a normal article. An "attention" or "cleanup" tag would be more appropriate. Deryck C. 2005-07-05 08:32:21 (UTC)

Eigenvector 10 August 2005

This article has a reasonable base, but is missing a broad overview, and several key topic areas. linas 1 July 2005 15:07 (UTC)

Support

1. This is something that many will be able to contribute to. Applications galore. My only concern is that the article is not that bad currently, but perhaps we should aim for a modest restart so that this collaboration does not collapse again. Jitse Niesen (talk) 3 July 2005 02:44 (UTC)
2. Deryck C. 16:06, 9 August 2005 (UTC) We should collaborate on the merged article series Eigenvalue, eigenvector, and eigenspace instead.

Comments:

• This article is being merged into Eigenvalue, eigenvector and eigenspace, so how about that instead? Josh Cherry 7 July 2005 02:30 (UTC)

Multiple comparisons 18 September 2005

A fairly important topic in applied statistics. Needs an expanded discussion of

• The relationship of percomparison error rate and family/experiment wise error rate
• Explanation of Post Hoc testing and the misconcenption of the need for a signficant ANOVA before doing MCPs.
• Expansion of the methods section, this should cover/have links to all the methods offered by SPSS/SAS
• An explanation of the concept of step-down/up procedures wich are the basis for modern Bonferroni based methods and the SNK method.
