Bayesian experimental design is a statistical approach that integrates Bayesian principles with the design of experiments. It focuses on the process of planning and conducting experiments in such a way that the data collected can provide the most informative insights regarding the parameters of interest. Here are some key elements of Bayesian experimental design: 1. **Prior Knowledge**: Bayesian methods allow the incorporation of prior information or beliefs about the parameters being studied. This prior knowledge can come from previous experiments, expert opinions, or literature.
A computer experiment refers to a structured process of testing, simulating, or analyzing phenomena using computational methods and resources. It typically involves the use of computer software and models to facilitate experiments that may be impractical, expensive, or impossible to conduct in a physical or real-world setting. Key aspects of computer experiments include: 1. **Modeling and Simulation:** Researchers create computational models that represent real-world systems.
Interrupted time series (ITS) is a type of statistical analysis used in research to evaluate the effects of an intervention or event over time. It is commonly used in fields like public health, social sciences, and economics to assess the impact of policy changes, program implementations, or other significant events on a specific outcome measured at multiple time points. ### Key Characteristics of Interrupted Time Series: 1. **Repeated Measure**: Data is collected at multiple time points both before and after the intervention or event.
Design–Expert is a statistical software application used primarily for designing experiments and analyzing the results of those experiments. It is widely utilized in various fields like manufacturing, pharmaceuticals, and food science to improve processes, product designs, and formulations through efficient experimentation. Key features of Design–Expert include: 1. **Factorial and Fractional Factorial Designs**: Users can design experiments that investigate the effects of multiple factors, including full and fractional factorial designs.
Drug design is a complex and iterative process in the field of medicinal chemistry and pharmacology that aims to discover and create new therapeutic compounds. It involves designing molecules that can interact with specific biological targets, such as proteins, enzymes, or receptors, to achieve a desired therapeutic effect. Key aspects of drug design include: 1. **Understanding Biological Targets**: Identifying and studying the biological targets associated with a particular disease is crucial.
Ignorability, often referred to in the context of causal inference and statistical modeling, refers to a condition under which the treatment assignment in an observational study can be considered as if it were randomized. This concept is crucial for identifying causal effects from observational data, as it allows researchers to make valid inferences about treatment effects without the biases typically associated with non-randomized studies.
Anti-de Sitter space (AdS) is a spacetime geometry that arises in the context of general relativity and is characterized by a constant negative curvature. It is one of the classical solutions to Einstein's field equations and is commonly used in theoretical physics, particularly in theories of gravity and in the study of gauge/gravity duality, particularly in the context of string theory and the holographic principle.
A field experiment is a research study conducted in a real-world setting rather than a controlled laboratory environment. This type of experiment aims to evaluate the effects of interventions, treatments, or manipulations on participants or conditions in their natural surroundings. Field experiments are often used in various disciplines, including social sciences, agriculture, ecology, and marketing, to test hypotheses and assess cause-and-effect relationships in a more natural context.
A manipulation check is a procedure used in experimental research to determine whether the manipulation of an independent variable has had the intended effect on participants. Essentially, it helps researchers verify that the experiment successfully influenced the participants in the way they intended.
Multiple baseline design is a type of research design commonly used in behavioral sciences, particularly in the field of psychology and education. It is primarily applied in single-subject research, but it can also be useful in small group settings. The key features of multiple baseline design include: 1. **Staggered Introduction**: The intervention or treatment is introduced at different times across multiple subjects, behaviors, or settings.
A longitudinal study is a research design that involves repeated observations of the same variables (such as individuals, groups, or phenomena) over an extended period of time, which can range from months to many years or even decades. Longitudinal studies are often used in various fields, including psychology, sociology, medicine, and education, to track changes and developments, identify trends, and examine causal relationships.
Bburago is a brand known for producing die-cast model vehicles. The company was founded in Italy in 1974 and has built a reputation for creating detailed and collectible scale models of cars, motorcycles, and other vehicles. Bburago models are often produced in various scales, with 1:18 and 1:24 being among the most popular. The brand is recognized for its partnerships with numerous automotive manufacturers, allowing it to create replicas of real-life vehicles.
The National Research Ethics Service (NRES) was a part of the UK's National Health Service (NHS) responsible for overseeing the ethical review of research involving human participants. Its primary aim was to ensure that research is conducted ethically, safeguarding the rights, dignity, and welfare of participants. NRES provided a framework for the review of healthcare and biomedical research protocols, ensuring compliance with ethical standards and regulations.
An observational study is a type of research method used in various fields, including medicine, social sciences, and epidemiology, where researchers observe and collect data on subjects without manipulating any variables or assigning treatments. In an observational study, the researcher does not control the environment or conditions under which the data is collected, and participants are not randomly assigned to different groups. There are several key characteristics of observational studies: 1. **No Intervention**: Researchers simply observe what is occurring naturally without trying to influence outcomes.
Orthogonal array testing is a statistical method used in software testing to systematically evaluate the interactions of multiple variables or factors with minimal test cases. This technique is particularly useful in situations where there are numerous combinations of input variables, making exhaustive testing impractical. ### Key Concepts: 1. **Orthogonal Arrays**: An orthogonal array is a structured way of arranging combinations of factors (variables) such that every pair of levels of each factor appears an equal number of times across all combinations.
Siku Toys is a well-known brand that specializes in producing high-quality die-cast model vehicles and toys. Founded in Germany in 1950, Siku is particularly recognized for its realistic and detailed miniatures, which often include vehicles such as cars, trucks, construction equipment, and agricultural machinery. The brand is popular among both children and collectors because of its commitment to durable materials and intricate designs that reflect real-life vehicles.
Pseudoreplication refers to an experimental design flaw where multiple measurements or observations are treated as independent when they are not. This often occurs when the same experimental unit is sampled multiple times without accounting for the lack of independence between measurements. As a result, statistical analyses can yield misleading conclusions because the variability and correlation among non-independent samples are not properly considered.
Random assignment is a key methodological technique used in experimental research to ensure that participants are evenly and randomly allocated to different groups or conditions within a study. The primary purpose of random assignment is to control for confounding variables and minimize selection bias, allowing researchers to make more valid inferences about cause-and-effect relationships. In a randomized controlled trial (RCT), for example, participants might be assigned to either an experimental group that receives the treatment being tested or a control group that does not receive the treatment.
The Scheirer–Ray–Hare test is a non-parametric statistical test used to analyze data in a two-way analysis of variance (ANOVA) framework, particularly when dealing with ordinal data or when the assumptions of normality for standard ANOVA are not met. It is often applied in the context of experimental designs that involve more than one independent variable.

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.
