Mean Absolute Scaled Error (MASE) is a metric used to evaluate the accuracy of forecasting methods. It provides a scale-free measure of forecasting accuracy, making it useful for comparing forecast performance across different datasets and scales.
The concept of "measuring economic worth over time" generally refers to assessing the value of an asset, investment, or economy by considering changes that occur over a specific period. This can involve various methodologies and approaches, depending on the context and what is being measured. Here are some key aspects related to this concept: 1. **Time Value of Money (TVM)**: This principle suggests that money available today is worth more than the same amount in the future due to its potential earning capacity.
A moving average crossover is a popular trading strategy used in technical analysis for identifying potential buy or sell signals in financial markets. It involves two or more moving averages of an asset's price, which help to smooth out price data and identify trends. ### Key Concepts: 1. **Moving Average (MA)**: This is a calculation that takes the average price of a security over a specific number of periods.
The order of integration refers to the number of times a function has been integrated. In calculus, the process of integration can be performed multiple times, and each layer of integration adds to the "order." Here’s a brief breakdown of the concept: 1. **First Order Integration**: This is the process of integrating a function once.
Seasonal adjustment is a statistical technique used to remove the effects of seasonal variations in time series data. Many economic and financial indicators, such as employment rates, retail sales, and production figures, often exhibit regular patterns that recur in a predictable manner at specific times of the year, such as holidays or harvest seasons. These seasonal variations can distort the underlying trends in the data. By applying seasonal adjustment, analysts aim to produce a clearer view of the underlying trends by isolating and removing these predictable seasonal influences.
Secular variation refers to the long-term changes or trends observed in a particular phenomenon over an extended period, typically spanning decades to centuries. This term is commonly used in various fields, such as geology, paleoclimatology, and even economics, to describe gradual changes that are not tied to periodic cycles (like seasonal or annual changes). In the context of geology and geomagnetism, secular variation may refer to the gradual changes in the Earth's magnetic field intensity and direction over time.
Smoothing is a statistical technique used to reduce noise and variability in data to reveal underlying patterns or trends. It is commonly applied in various fields, such as signal processing, time series analysis, data visualization, and machine learning. The goal of smoothing is to make the important features of the dataset more apparent, allowing for clearer insights and analysis.
A **stationary distribution** is a concept primarily used in the context of Markov chains and stochastic processes. It refers to a probability distribution that remains unchanged as time progresses. In other words, if the system is in the stationary distribution, the probabilities of being in each state do not change over time.
A trend-stationary process is a type of time series that exhibits a deterministic trend but is stationary around that trend. This means that while the time series data may have a long-term upward or downward trend, the fluctuations around this trend are stationary, characterized by constant mean and variance over time.
J-PARC, or the Japan Proton Accelerator Research Complex, is a large research facility located in Tokai, Japan. It is a joint project of the Japan Atomic Energy Agency (JAEA) and the High Energy Accelerator Research Organization (KEK). The facility is designed for various types of experiments in particle physics, nuclear physics, and materials science.
Kronecker's theorem, also known as the Kronecker limit formula, is a result in number theory specifically related to the distribution of prime numbers and the behavior of certain algebraic objects. It can be particularly focused on the context of the theory of partitions or modular forms, but the term might refer to different results depending on the field.
The term "total set" can refer to different concepts depending on the context in which it is used. Here are a few possibilities: 1. **Mathematics**: In set theory, a "total set" might refer to a comprehensive collection of elements that encompasses all possible members of a certain type or category. For instance, the set of all integers, the set of real numbers, or the set of all elements in a given operation can be considered total in their respective contexts.
"More of Tom Lehrer" is a comedy album by the American singer-songwriter and mathematician Tom Lehrer, released in 1961.

This album includes some of Lehrer’s well-known songs, showcasing his clever lyrics and distinctive style that blend humor with sharp wit.
"Revisited" is a compilation album by American satirical songwriter Tom Lehrer, released in 1960. The album features a selection of Lehrer’s well-known songs, showcasing his unique blend of wit, humor, and musical talent. It includes tracks that cover various subjects, often highlighting social and political themes of the time with a humorous and satirical edge. The album has become a classic in Lehrer's discography and is representative of his style, characterized by clever lyrics and catchy melodies.
"Storm Track" can refer to several different contexts, but it generally relates to the monitoring and forecasting of weather patterns, particularly severe weather events like hurricanes, tornadoes, or winter storms. Here are a few possible interpretations: 1. **Meteorology**: In meteorological terms, a storm track indicates the path that a storm system is expected to follow as it moves through a particular area.
Mijos is a term that can refer to various things, but without more context, it is difficult to pinpoint exactly what you are asking about. It could refer to: 1. **Geographical Location**: There may be a place named Mijos in certain countries, although it is not widely recognized. 2. **Culinary Dish**: In some cultures, it may refer to a traditional dish or food item, possibly a regional variant of another dish.
Parker Brothers is an American toy and game company established in 1883 by George S. Parker, Charles Parker, and Edward Parker. It became widely known for producing classic board games, including "Monopoly," "Clue" (known as "Cluedo" in some regions), "Risk," and "Sorry!" Over the years, Parker Brothers has contributed significantly to the gaming industry, creating games that have become beloved household staples.
Tonka Films, often associated with the Tonka brand, is a division known for producing children's television shows and films. The Tonka name is primarily recognized for its line of toy trucks and construction vehicles, which have been popular for decades.

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.
