Welcome
Hello , and welcome to Wikipedia. Thank you for your contributions. I hope you like the place and decide to stay. Here are a few good links for newcomers: I hope you enjoy editing here and being a Wikipedian! By the way, you can sign your name on Talk and vote pages using three tildes, like this: &#x007e;&#x007e;&#x007e;. Four tildes (&#x007e;&#x007e;&#x007e;&#x007e;) produces your name and the current date. If you have any questions, see the help pages, add a question to the village pump or ask me on my Talk page.

TeX scratch
Here are some TeX examples for when I need to format math in WikiPedia:

$$\frac{a}{b}$$

$$ {-b\pm\sqrt{b^2-4ac} \over {2a}} $$

Commons Images
Hey, I just saw your question about using images from the Commons here on Wikipedia. I had the exact same question once upon a time, so I know where you're coming from. Interestingly enough, using an image from the Commons is just like using an image that you had uploaded directly to Wikipedia. Simply use and the image will show up in the article. You can include other typical image tag options as necessary. For an example of an article that uses an image from the Commons, check out Arica. Let me know if you have any other questions as I would be more than happy to help. --Hetar 08:24, 10 April 2006 (UTC)

Table
Give me some time, I have to check it out and that will cost some days. I will check both the table and the pages (sometimes the pages will have to change). It will take some days. Electionworld = Wilfried (talk 13:51, 1 August 2006 (UTC) This is the result: List of political parties in Bahrain No difference - List of political parties in Bangladesh changed list - List of political parties in Belarus No difference - List of political parties in Benin changed article - List of political parties in Botswana changed list - List of political parties in Burkina Faso changed article

 * List of political parties by UN geoscheme I have broken up this huge list into several sub-list by UN Geoscheme, because the single massive list is a clear violation of WP:SIZE. I have ratined the table format you proposed and became consensus. However, this has been reverted without discussion by other editors, with my restores. I ask you to please comment on the talk page.--Cerejota 19:32, 16 June 2007 (UTC)

random effects model
Your statement was backwards: the random effects model is not a special case of the fixed-effects model; rather the fixed-effects model is a special case of the random-effeects model. If you say "A is a special case of B", you're saying ever A is B (but some B may be non-A)". Michael Hardy 19:00, 18 April 2007 (UTC)

 * Hi Michael, I don't want to be pedantic, and I don't claim my edits were excellent, but from what I know about these models, random effects models incorporate all assumptions of fixed effects models, with the additional assumption that the individual effects (which are still fixed for each individual) are drawn from a specific random distribution, rather than no restrictions being placed on these values. According to this understanding, there are some models that conform to the fixed effects assumptions but not to the random effects assumptions, and thus random effects are a special case of the fixed effects model.

 * random effects models incorporate all assumptions of fixed effects models
 * Certainly they do not. Fixed-effect models assume the effect are fixed.  Random-effects models do not.


 * with the additional assumption that the individual effects (which are still fixed for each individual) are drawn from a specific random distribution
 * Fixed-effects models also have that assumption, the distribution being degenerate, i.e. concentrating all probability at a point.


 * there are some models that conform to the fixed effects assumptions but not to the random effects assumptions, and thus random effects are a special case of the fixed effects model.
 * If there were models conforming to fixed-effects assumptions but not to random-effects assumptions, that would not mean that random-effects models are a special case of fixed-effects models. To say "A is a special case of B" means that every A is a B.  In this case that would mean "every random-effects model is a fixed-effects model".  That's not true.
 * In fact, if you just say the variance is 0 in a random-effects model, you've got a fixed-effects model. If you drop the assumption that the variance is 0, you've got a random-effects model that is not a fixed-effects model. Michael Hardy 11:59, 11 July 2007 (UTC)

 * Thanks for your comments on special cases and logic rules. However, our disagreement does not stem from problems with such rules, but from a fundamental disagreement about what fixed and random effects estimation involves. I believe quite firmly that a "random-effects model with the additional assumption that the variance of the random effect is zero" results in a regular OLS model, not in a fixed-effects model. This disagreement could originate in me being wrong, you being wrong, or there being more than one definition of fixed-effects and random-effects models floating around out there. I will not be editing the corresponding web pages further, but hope that someone will be able to clarify this with a third opinion, in a clear and convincing manner. -- Torfason 21:27, 17 July 2007 (UTC)

Myerchin marlinspike
Hello Torfason, thanks for the feedback! The pictured spike is made by Myerchin, Inc. I got mine as part of a set with the fixed-blade rigging knife that they sell, although with a nylon sheath rather than the leather they make now. The spike is the "A008" and with a sheath "A009". They are available from the company here and also on Amazon and other places... Regards, --Dfred (talk) 18:44, 6 March 2013 (UTC)
