Kriging is a statistical interpolation technique used extensively in geostatistics, spatial analysis, and various fields such as mining, environmental science, and agriculture. It allows for the estimation of unknown values at specific locations based on known data points, taking into account both the distance and the spatial arrangement of the points. Developed by the South African engineer Danie G. Krige in the 1950s, Kriging uses a method based on the spatial correlation of the data.

Known for his involvement in local and national politics, Dimitrakopoulos has focused on issues pertinent to his constituents and the broader Greek community.
The reference class problem is a concept often discussed in the context of probability, forecasting, and decision-making. It arises when trying to make predictions based on past events by selecting a suitable reference class or category to which a current situation belongs. The problem stems from the challenge of selecting the right reference class, as different choices can lead to different probabilities and conclusions about the likelihood of future events.
The "List of Guidances for Statistics in Regulatory Affairs" typically refers to a compilation of documents and guidelines provided by regulatory agencies that address statistical methods and best practices for the design, analysis, and interpretation of clinical trials and other research studies in the context of drug and device approval. These guidelines are essential to ensure that statistical analyses meet the necessary standards to support regulatory submissions.
The "Preventable fraction among the unexposed" (also known as the "attributable fraction among the unexposed") is a measure used in epidemiology to quantify the proportion of disease in a population that can be attributed to a specific risk factor within the group of individuals who are not exposed to that risk factor.
Verification bias occurs in research, particularly in diagnostic studies, when there is a systematic difference in how the outcomes of a diagnostic test are verified based on the results it produces. Essentially, it arises when the methods used to confirm or validate the accuracy of a test depend on the test's initial results, leading to potentially distorted or skewed findings.
Engel's theorem is a result in the field of geometry, specifically concerning the relationships between the angles formed by a polygon's diagonals.
An instrument mechanic is a skilled technician who specializes in the installation, maintenance, calibration, and repair of instruments and instrumentation systems used in various industries. These professionals are crucial in sectors such as manufacturing, petrochemical, pharmaceuticals, and power generation, where precise measurements and controls are essential for operations. ### Key Responsibilities: 1. **Installation**: Setting up various instruments and control systems, including sensors, transmitters, and control panels.
Nikolay Krylov (1879-1955) was a prominent Russian mathematician known for his contributions to various areas of mathematics, particularly in functional analysis, differential equations, and the theory of boundary value problems. He made significant advancements in the development of the theory related to partial differential equations and contributed to the field of numerical analysis.
A Verma module is a type of representation of a highest weight module in the context of the representation theory of Lie algebras, particularly those that are semisimple. Verma modules play an important role in the study of the structure and representation theory of Lie algebras and quantum groups.
The Focal Subgroup Theorem is a concept in the area of algebraic topology and group theory, particularly relating to finite group actions and their relationships to fixed point sets in topological spaces. In more detail, the Focal Subgroup Theorem often pertains to the study of groups acting on topological spaces and examines the interaction between the group action and the topology of the space.
Complex representation refers to the method of expressing mathematical or physical concepts using complex numbers, which are numbers that have both a real part and an imaginary part.
The Dynkin index, also known as the Dynkin index of a representation, is a concept that arises in the study of Lie algebras and Lie groups, particularly in the context of representation theory. It provides a way to quantify the degree of "mixing" or "interaction" of a representation with the structure of the algebra, especially when considering the space of invariant functions or the geometry associated with the representation.
Scrabble 2007 Edition refers to a specific version of the classic board game Scrabble, which was released in 2007. This edition maintains the traditional gameplay of Scrabble, where players create words on a game board using letter tiles, with each letter having a specific point value. In terms of features, the 2007 Edition may have included updated components such as modernized tile designs, a new design for the game board, or specific rule adjustments.
In poker, "steal" refers to a strategy where a player attempts to win the pot by making a bet or raise when they believe their opponents are likely to fold, rather than because they have a strong hand. This tactic is commonly employed during the late stages of a tournament or in a cash game, particularly when the blinds are high and players may be more inclined to conserve their chips.
An excavated dodecahedron is a geometric shape derived from a regular dodecahedron, which is a three-dimensional polyhedron with twelve flat faces, each of which is a regular pentagon. The term "excavated" typically refers to the process of removing material from the solid, resulting in a polyhedron that has indentations or cavities.
A bifrustum is a geometric shape that can be considered as a variant of a frustum. Specifically, it is formed by taking two frustums of identical cross-sectional shapes and placing them back to back. Each half of a bifrustum resembles a frustum, which is the portion of a solid (typically a cone or pyramid) that lies between two parallel planes.
A prismatoid is a specific type of polyhedron that can be considered as a generalized prism. In geometry, a prismatoid is defined as a three-dimensional solid that has two parallel faces (called bases) that can be any polygon and all other faces that are trapezoidal or triangular. Essentially, it has a structure where the top and bottom faces are connected in such a way that they aren't necessarily congruent or identical in shape.
The compound of five small rhombihexahedra is a complex geometric arrangement that consists of five small rhombihexahedra, which are dual to the cuboctahedron. Each rhombihexahedron is a polyhedron with 12 faces (6 rhombic and 6 square), and when combined in this compound, they create an intricate mathematical structure.

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!
We have two killer features:
  1. 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-calculus
    Articles 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.
