Logit analysis, also known as logistic regression, is a statistical method commonly used in marketing to model the relationship between a binary dependent variable and one or more independent variables. In marketing context, this analysis is particularly useful for predicting outcomes that can be categorized into two distinct classes, such as customer purchase behavior (buy vs. not buy), response to a marketing campaign (respond vs. not respond), or subscription to a service (subscribe vs. not subscribe).
Optimized Consumer Intensity Analysis (OCIA) is a method used primarily in the context of market research, consumer behavior analysis, and business strategy. While the term may not be widely standardized across all industries, it generally relates to analyzing how intensely consumers engage with a product or brand, and it aims to optimize this engagement for better business outcomes.
Preference regression is a statistical technique used to model and analyze preferences expressed by individuals, often in the context of decision-making or consumer behavior. The method applies regression analysis to preferences rather than traditional dependent variables, enabling researchers to explore how various factors influence the choices or rankings that individuals give to different alternatives. Here are some key aspects of preference regression: 1. **Purpose**: Preference regression aims to understand the relationship between individual characteristics (independent variables) and their expressed preferences (dependent variables).
The "Homicidal Chauffeur Problem" is a well-known concept in the field of motion planning and robotics, specifically within the area of control theory and game theory. It addresses a scenario where a "chauffeur" (or driver) is trying to evade a pursuer while navigating through a defined environment. The pursuer typically seeks to capture or reach the chauffeur, who is attempting to avoid being caught.
A pursuit curve is a type of mathematical curve that describes the path taken by a pursuer attempting to catch a moving target. In the context of pursuit curves, the pursuer moves in a way that continually adjusts its direction toward the target, which may also be moving. The classic example involves two entities: a pursuer and a target.
Trajectory optimization is a mathematical and computational approach used to determine the most efficient path or sequence of states (trajectories) that a system should follow over time to achieve specific goals while satisfying certain constraints. This concept is commonly applied in various fields, including robotics, aerospace, control systems, and biomechanics. ### Key Aspects of Trajectory Optimization: 1. **Objective Function**: The optimization process typically involves minimizing or maximizing an objective function, which quantifies the performance of the trajectory.
Pseudospectral optimal control is a mathematical and computational approach used to solve optimal control problems. It combines the principles of pseudospectral methods with optimal control theory to find control inputs that minimize or maximize a given cost function while satisfying dynamic constraints defined by differential equations.
Shape optimization is a mathematical and computational process aimed at finding the best shape or geometry of a physical object to achieve specific performance criteria or objectives. This is commonly used in various fields including engineering, design, and architecture, where the shape of an object can significantly influence its behavior, performance, and efficiency. ### Key aspects of shape optimization: 1. **Objective Function**: In shape optimization, an objective function is defined that quantifies the performance measure to be optimized.
Real-time gross settlement (RTGS) is a system for transferring funds from one bank to another on a "real-time" basis. In an RTGS system, the settlement of fund transfers occurs in real-time, meaning that transactions are settled immediately as they are processed, rather than being aggregated and settled at the end of a certain period.
Remote diagnostics refers to the use of technology to assess and diagnose issues in systems, devices, or machinery from a distance. This process typically involves gathering data from the system through sensors or software and transmitting that information to a specialist or diagnostic software for analysis.
Whiteboard animation is a style of animated video that simulates the process of drawing on a whiteboard. Typically, these animations involve a hand (realistic or digital) that appears to draw images, illustrations, and text on a white background, all while a voiceover or background music accompanies the visuals. This technique is often used for educational purposes, marketing, or storytelling.
Wolf tone refers to an unpleasant, beating sound that can occur when a musical instrument, particularly string instruments like violins, cellos, or pianos, produces certain pitches that resonate in a way that interferes with other frequencies. This resonance can create a dissonant response that some musicians find harsh or undesirable.
Heterostasis is a concept from cybernetics that refers to the ability of a system to maintain stability through adaptation and change. Unlike homeostasis, which focuses on maintaining equilibrium or stability within a system by counteracting disturbances, heterostasis acknowledges that systems must sometimes adjust or change their functioning in response to varying external conditions in order to maintain overall stability. In cybernetic terms, heterostasis emphasizes the dynamic interactions and feedback loops that allow a system to respond effectively to external influences and changes.
Joseph Farcot was a French mathematician and engineer known for his work in the 19th century. He made contributions primarily in the fields of applied mathematics and engineering, particularly in the areas of mechanics and hydrostatics. One of his notable achievements was his development of the "Farcot's Theorem" related to the equilibrium of elastic beams. However, details about his contributions might not be widely recognized compared to other mathematicians of his time.
The Zero-Truncated Poisson (ZTP) distribution is a probability distribution that is derived from the Poisson distribution by removing the zero-count outcomes. This modification is useful in scenarios where the occurrence of an event is guaranteed to be at least one, hence no observations of zero are possible.
A Faro shuffle, also known as a perfect shuffle, is a card shuffling method that interleaves two halves of a deck of cards in a precise manner. There are two types: the "in shuffle" and the "out shuffle." 1. **In Shuffle**: In this variation, the top card of the original deck remains in the top position after the shuffle.
A permutation group is a mathematical concept in group theory that consists of a set of permutations of a given set combined with the operation of composition. Here's a more detailed breakdown of the concept: 1. **Permutations**: A permutation of a set is a rearrangement of its elements. For a finite set with \( n \) elements, a permutation is simply a bijective function from the set to itself.
Bessel functions are a family of solutions to Bessel's differential equation, which arises in various problems in mathematical physics, particularly in wave propagation, heat conduction, and static potentials. The equation is typically expressed as: \[ x^2 y'' + x y' + (x^2 - n^2) y = 0 \] where \( n \) is a constant, and \( y \) is the function of \( x \).
The Cunningham function, often denoted as \( C_n \), is a sequence of numbers defined as follows: - \( C_0 = 1 \) - \( C_1 = 1 \) - For \( n \geq 2 \), \( C_n = 2 \cdot C_{n-1} + C_{n-2} \) This recurrence relation means that each term is generated by taking twice the previous term and adding the term before that.
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.

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.
