"Statistics stubs" generally refers to short or incomplete articles related to statistical concepts, methods, or data that are typically found on platforms like Wikipedia. These stubs usually contain minimal information about a topic, serving as a placeholder for more detailed content to be developed later. In the context of Wikipedia, a "stub" can encourage users to expand on the topic by providing additional information, references, and context.
In the context of probability and statistics, "stubs" can refer to a few different concepts depending on the field and context in which the term is used. However, "probability stubs" is not a widely recognized term in probability theory or statistics; it might be a misunderstanding or a specialized term used in a specific context, such as a proprietary framework or software.
In the context of Wikipedia and other collaborative encyclopedic platforms, a "stub" is a short or incomplete article that could be expanded to provide more detailed and comprehensive information. Stub templates are predefined snippets of code that editors can add to articles to indicate that the content is insufficient and invite users to contribute more information. Mathematics stub templates specifically refer to stubs related to mathematical topics. They are used to flag articles that need improvement in order to meet the standards of a full, informative entry.
Uniform tilings in the hyperbolic plane are arrangements of hyperbolic shapes that cover the entire hyperbolic plane without any gaps or overlaps while exhibiting a regular and repeating pattern. These tilings are characterized by their symmetry and regularity, often defined by their vertex configuration and the types of shapes used in the tiling. In mathematical terms, a uniform tiling can be described as a tessellation of the hyperbolic plane using polygonal shapes that can be generalized by their vertex configurations.
The Table of Lie Groups consists of a classification of Lie groups based on their dimension and properties. Lie groups are smooth manifolds that also have a group structure, and they play a significant role in various areas of mathematics and theoretical physics, particularly in the study of symmetries. There are several types of Lie groups, but they can generally be categorized into a few main classes. Here’s a simplified overview: 1. **Compact Lie Groups**: These groups are closed and bounded.
The "sum of squares" is a statistical concept used to measure the variability or dispersion in a dataset. It is calculated by taking the difference between each data point and the mean of the dataset, squaring those differences, and then summing them up. It can be used in various contexts, including inferential statistics, regression analysis, and the analysis of variance (ANOVA). ### Formula Given a dataset with \( n \) observations \( x_1, x_2, ...

The list of uniform polyhedra refers to a classification of polyhedra that are highly symmetrical, including both regular polyhedra (Platonic solids) and less regular forms that still exhibit a uniform structure. These polyhedra are defined by having faces that are composed of regular polygons and all vertices having the same type of arrangement of faces.
Systems theory is an interdisciplinary study that emphasizes the relationships and interactions within and between systems. It has applications in various fields, including biology, engineering, social sciences, environmental science, and management. Here’s a list of different types or branches of systems theory: 1. **General Systems Theory**: Proposed by Ludwig von Bertalanffy, it focuses on the common principles that govern all systems, regardless of their nature.
Triangle inequalities refer to a set of mathematical inequalities that describe the relationships between the lengths of the sides of a triangle. The most fundamental triangle inequalities assert that for any triangle with side lengths \(a\), \(b\), and \(c\): 1. \(a + b > c\) (the sum of the lengths of any two sides must be greater than the length of the third side) 2. \(a + c > b\) 3.
The term "list of transforms" can refer to various contexts, especially in mathematics, computer science, and signal processing. Below are some interpretations of what a "list of transforms" could entail: ### 1. Mathematical Transforms: - **Fourier Transform**: Converts a function of time (or space) into a function of frequency. - **Laplace Transform**: Used to analyze linear time-invariant systems, transforming a function of time into a complex frequency domain.
A "fundamental theorem" typically refers to a statement that is foundational and essential to a particular area of mathematics or science. Such theorems often establish critical relationships, properties, or structures within that field. Here are a few well-known fundamental theorems across various domains: 1. **Fundamental Theorem of Arithmetic**: Every integer greater than 1 can be uniquely factored into prime numbers, up to the order of the factors.
A list of theorems can vary widely depending on the field of study within mathematics or other disciplines. Below is a selection of notable theorems across various areas of mathematics: ### Arithmetic and Number Theory 1. **Fundamental Theorem of Arithmetic**: Every integer greater than 1 can be expressed as a product of prime numbers in a unique way. 2. **Euclid's Theorem**: There are infinitely many prime numbers.
A list of tessellations refers to various patterns or arrangements that fill a plane without any gaps or overlaps.

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
