Seemingly Unrelated Regressions
In econometrics, the seemingly unrelated regressions (SUR) or seemingly unrelated regression equations (SURE) model, proposed by Arnold Zellner in (1962), is a generalization of a linear regression model that consists of several regression equations, each having its own dependent variable and potentially different sets of exogenous explanatory variables. Each equation is a valid linear regression on its own and can be estimated separately, which is why the system is called ''seemingly unrelated'', although some authors suggest that the term ''seemingly related'' would be more appropriate, since the error terms are assumed to be correlated across the equations. The model can be estimated equation-by-equation using standard ordinary least squares (OLS). Such estimates are consistent, however generally not as efficient as the SUR method, which amounts to feasible generalized least squares with a specific form of the variance-covariance matrix. Two important cases when SUR is in fact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Series Of Unsurprising Results In Economics
''Series of Unsurprising Results in Economics'' (''SURE'') is an academic journal about economics published by University of Canterbury. The journal's purpose is to provide an outlet for valid research papers about economics that endeavors to counter a publication bias In published academic research, publication bias occurs when the outcome of an experiment or research study biases the decision to publish or otherwise distribute it. Publishing only results that show a significant finding disturbs the balance o ... favoring research that contains sensational findings. Instead, reliable research with relatively low-key results is the focus to provide a legitimate forum for it that otherwise would be rejected by other editors.

Economics
Economics () is the social science that studies the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption of goods and services. Economics focuses on the behaviour and interactions of Agent (economics), economic agents and how economy, economies work. Microeconomics analyzes what's viewed as basic elements in the economy, including individual agents and market (economics), markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyzes the economy as a system where production, consumption, saving, and investment interact, and factors affecting it: employment of the resources of labour, capital, and land, currency inflation, economic growth, and public policies that have impact on glossary of economics, these elements. Other broad distinctions within economics include those between positive economics, desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Journal
An academic journal or scholarly journal is a periodical publication in which scholarship relating to a particular academic discipline is published. Academic journals serve as permanent and transparent forums for the presentation, scrutiny, and discussion of research. They nearly-universally require peer-review or other scrutiny from contemporaries competent and established in their respective fields. Content typically takes the form of articles presenting original research, review articles, or book reviews. The purpose of an academic journal, according to Henry Oldenburg (the first editor of ''Philosophical Transactions of the Royal Society''), is to give researchers a venue to "impart their knowledge to one another, and contribute what they can to the Grand design of improving natural knowledge, and perfecting all Philosophical Arts, and Sciences." The term ''academic journal'' applies to scholarly publications in all fields; this article discusses the aspects common to all ac ...

Certainty
Certainty (also known as epistemic certainty or objective certainty) is the epistemic property of beliefs which a person has no rational grounds for doubting. One standard way of defining epistemic certainty is that a belief is certain if and only if the person holding that belief could not be mistaken in holding that belief. Other common definitions of certainty involve the indubitable nature of such beliefs or define certainty as a property of those beliefs with the greatest possible justification. Certainty is closely related to knowledge, although contemporary philosophers tend to treat knowledge as having lower requirements than certainty. Importantly, epistemic certainty is not the same thing as psychological certainty (also known as subjective certainty or certitude), which describes the highest degree to which a person could be convinced that something is true. While a person may be completely convinced that a particular belief is true, and might even be psychologicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sure (brand)
Rexona is an Australian deodorant and antiperspirant brand, owned by British conglomerate Unilever.

Telephone Company
A telephone company, also known as a telco, telephone service provider, or telecommunications operator, is a kind of communications service provider (CSP), more precisely a telecommunications service provider (TSP), that provides telecommunications services such as telephony and data communications access. Many telephone companies were at one time government agencies or privately owned but state-regulated monopolies. The government agencies are often referred to, primarily in Europe, as PTTs (postal, telegraph and telephone services). Telephone companies are common carriers, and in the United States are also called local exchange carriers. With the advent of mobile telephony, telephone companies now include wireless carriers, or mobile network operators. Most telephone companies now also function as internet service providers (ISPs), and the distinction between a telephone company and an ISP may disappear completely over time, as the current trend for supplier convergence in ...

British Overseas Territories
The British Overseas Territories (BOTs), also known as the United Kingdom Overseas Territories (UKOTs), are fourteen dependent territory, territories with a constitutional and historical link with the United Kingdom. They are the last remnants of the former British Empire and do not form part of the United Kingdom itself. The permanently inhabited territories are internally Self-governance, self-governing, with the United Kingdom retaining responsibility for Defence (military), defence and foreign relations.

Stein's Unbiased Risk Estimate
In statistics, Stein's unbiased risk estimate (SURE) is an unbiased estimator of the mean-squared error of "a nearly arbitrary, nonlinear biased estimator." In other words, it provides an indication of the accuracy of a given estimator. This is important since the true mean-squared error of an estimator is a function of the unknown parameter to be estimated, and thus cannot be determined exactly. The technique is named after its discoverer, Charles Stein. Formal statement Let \mu \in ^d be an unknown parameter and let x \in ^d be a measurement vector whose components are independent and distributed normally with mean \mu_i, i=1,...,d, and variance \sigma^2. Suppose h(x) is an estimator of \mu from x, and can be written h(x) = x + g(x), where g is weakly differentiable. Then, Stein's unbiased risk estimate is given by :\operatorname(h) = d\sigma^2 + \, g(x)\, ^2 + 2 \sigma^2 \sum_^d \frac g_i(x) = -d\sigma^2 + \, g(x)\, ^2 + 2 \sigma^2 \sum_^d \frac h_i(x), where g_i(x) is t ...

Sauer
The Sauer (German and Luxembourgish, , ) or Sûre ( French, ) is a river in Belgium, Luxembourg and Germany. A left tributary of the Moselle, its total length is . Rising near Vaux-sur-Sûre in the Ardennes in southeastern Belgium, the Sauer flows eastwards and becomes the border with Luxembourg near Martelange. It forms the border between Belgium and Luxembourg for north of Martelange. West of Esch-sur-Sûre it flows into an artificial lake, the Upper Sûre Lake created by the Esch-sur-Sûre Dam, which gives its (French) name to the Luxembourgian commune of Lac de la Haute-Sûre. After flowing through Ettelbruck and Diekirch, the Sauer forms the border between Luxembourg and Germany for the last of its course, passing Echternach before emptying into the Moselle in Wasserbillig. The rivers Wiltz, Alzette, White Ernz, Black Ernz, Our Our or OUR may refer to: * The possessive form of " we" * Our (river), in Belgium, Luxembourg, and Germany * Our, Belgium, a village in Bel ...
