Martin-Quinn Score
Martin-Quinn scores or M-Q scores are dynamic metrics used to gauge the ideology of a U.S. Supreme Court Justice based on their voting record. Therefore, a jurist's score will continuously change, unlike static measures of ideology such as the Segal–Cover score and Judicial Common Space score. Martin-Quinn scores are among the most commonly used measures of judicial ideology. History and method The concept of the Martin-Quinn score was published in a 2002 paper by Andrew D. Martin and Kevin M. Quinn. The Martin-Quinn score uses Markov chain Monte Carlo (MCMC) methods to fit a Bayesian model of ideal points. The ideal points can change over time due to the item response model. MQ scores are theoretically unbounded (have no minimum or maximum values). MQ scores are dynamic, as each decision made by a judge creates another data point that can be integrated into the model. The MQ score places the justices on a continuum of more liberal to more conservative. As of 2007, scores rough ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Segal–Cover Score
A Segal–Cover score is an attempt to measure the "perceived qualifications and ideology" of nominees to the United States Supreme Court. The scores are created by analyzing pre-confirmation newspaper editorials regarding the nominations from ''The New York Times'', ''Washington Post'', ''Chicago Tribune'', ''Los Angeles Times'', ''St. Louis Post-Dispatch'', and ''The Wall Street Journal''. Each nominee receives two scores that range from 0 to 1 based on the average score of all articles from these sources: * Qualifications: 0 means unqualified and 1 means extremely qualified ** Qualification scores are based on the characterization of each editorial as positive, neutral, or negative toward the nominee. Positive articles are coded as 1, neutral articles as 0.5, and negative articles as 0. * Ideology: 0 means most conservative, and 1 means most liberal. ** Ideology scores are based on each editorial's characterization of the nominee as liberal, moderate, conservative, or not applic ...

Judicial Common Space
The Judicial Common Space (JCS) is a strategy to compare the ideologies of American judges. It was developed to compare the viewpoints of judges in the US Supreme Court and the Court of Appeals. It is one of the most commonly used measures of judicial ideology. History The Judicial Common Space was developed by Lee Epstein, Andrew D. Martin, Jeffrey A. Segal, and Chad Westerland. It developed over a series of conferences and publications from 2005 through 2007, and was based on the NOMINATE Common Space score. NOMINATE was developed in 1997 to compare the political ideologies of members of Congress and Presidents. It also integrated Martin-Quinn scores, developed in 2002 to provide a voting-based ideological comparison of Supreme Court justices. Method The Judicial Common Space is based on the finding that a judge's rulings are often similar in ideology to the person who appointed the judge. The JCS factors in the ideology scores of the president, as well as both senators fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andrew D
Andrew is the English form of a given name common in many countries. In the 1990s, it was among the top ten most popular names given to boys in English-speaking countries. "Andrew" is frequently shortened to "Andy" or "Drew". The word is derived from the el, Ἀνδρέας, ''Andreas'', itself related to grc, ἀνήρ/ἀνδρός ''aner/andros'', "man" (as opposed to "woman"), thus meaning "manly" and, as consequence, "brave", "strong", "courageous", and "warrior". In the King James Bible, the Greek "Ἀνδρέας" is translated as Andrew. Popularity Australia In 2000, the name Andrew was the second most popular name in Australia. In 1999, it was the 19th most common name, while in 1940, it was the 31st most common name. Andrew was the first most popular name given to boys in the Northern Territory in 2003 to 2015 and continuing. In Victoria, Andrew was the first most popular name for a boy in the 1970s. Canada Andrew was the 20th most popular name chosen for mal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Markov Chain Monte Carlo
In statistics, Markov chain Monte Carlo (MCMC) methods comprise a class of algorithms for sampling from a probability distribution. By constructing a Markov chain that has the desired distribution as its equilibrium distribution, one can obtain a sample of the desired distribution by recording states from the chain. The more steps that are included, the more closely the distribution of the sample matches the actual desired distribution. Various algorithms exist for constructing chains, including the Metropolis–Hastings algorithm. Application domains MCMC methods are primarily used for calculating numerical approximations of multi-dimensional integrals, for example in Bayesian statistics, computational physics, computational biology and computational linguistics. In Bayesian statistics, the recent development of MCMC methods has made it possible to compute large hierarchical models that require integrations over hundreds to thousands of unknown parameters. In rare even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayesian Statistics
Bayesian statistics is a theory in the field of statistics based on the Bayesian interpretation of probability where probability expresses a ''degree of belief'' in an event. The degree of belief may be based on prior knowledge about the event, such as the results of previous experiments, or on personal beliefs about the event. This differs from a number of other interpretations of probability, such as the frequentist interpretation that views probability as the limit of the relative frequency of an event after many trials. Bayesian statistical methods use Bayes' theorem to compute and update probabilities after obtaining new data. Bayes' theorem describes the conditional probability of an event based on data as well as prior information or beliefs about the event or conditions related to the event. For example, in Bayesian inference, Bayes' theorem can be used to estimate the parameters of a probability distribution or statistical model. Since Bayesian statistics treats probabi ...

Item Response Theory
In psychometrics, item response theory (IRT) (also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables. It is a theory of testing based on the relationship between individuals' performances on a test item and the test takers' levels of performance on an overall measure of the ability that item was designed to measure. Several different statistical models are used to represent both item and test taker characteristics. Unlike simpler alternatives for creating scales and evaluating questionnaire responses, it does not assume that each item is equally difficult. This distinguishes IRT from, for instance, Likert scaling, in which ''"''All items are assumed to be replications of each other or in other words items are considered to be parallel instruments".A. van Alphen, R. Halfens, A. Hasman and T. Imbos. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Rehnquist
William Hubbs Rehnquist ( ; October 1, 1924 – September 3, 2005) was an American attorney and jurist who served on the U.S. Supreme Court for 33 years, first as an associate justice from 1972 to 1986 and then as the 16th chief justice from 1986 until his death in 2005. Considered a staunch conservative, Rehnquist favored a conception of federalism that emphasized the Tenth Amendment's reservation of powers to the states. Under this view of federalism, the Court, for the first time since the 1930s (with the exception of ''National League of Cities v. Usery'', which was overruled in '' Garcia v. San Antonio Metropolitan Transit Authority''), struck down an act of Congress as exceeding its power under the Commerce Clause. Rehnquist grew up in Milwaukee, Wisconsin, and served in the U.S. Army Air Forces during the final years of World War II. After the war's end in 1945, he studied political science at Stanford University and Harvard University, then attended Stanford Law Sc ...

Thurgood Marshall
Thurgood Marshall (July 2, 1908 – January 24, 1993) was an American civil rights lawyer and jurist who served as an associate justice of the Supreme Court of the United States from 1967 until 1991. He was the Supreme Court's first African-American justice. Prior to his judicial service, he was an attorney who fought for civil rights, leading the NAACP Legal Defense and Educational Fund. Marshall coordinated the assault on racial segregation in schools. He won 29 of the 32 civil rights cases he argued before the Supreme Court, culminating in the Court's landmark 1954 decision in ''Brown v. Board of Education'', which rejected the separate but equal doctrine and held segregation in public education to be unconstitutional. President Lyndon B. Johnson appointed Marshall to the Supreme Court in 1967. A staunch liberal, he frequently dissented as the Court became increasingly conservative. Born in Baltimore, Maryland, Marshall attended Lincoln University and the Howard Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarence Thomas
Clarence Thomas (born June 23, 1948) is an American jurist who serves as an associate justice of the Supreme Court of the United States. He was nominated by President George H. W. Bush to succeed Thurgood Marshall and has served since 1991. After Marshall, Thomas is the second African American to serve on the Court and its longest-serving member since Anthony Kennedy's retirement in 2018. Thomas was born in Pin Point, Georgia. After his father abandoned the family, he was raised by his grandfather in a poor Gullah community near Savannah.

Ideological Leanings Of United States Supreme Court Justices
The Supreme Court of the United States is the country's highest federal court. Established pursuant to Article Three of the U.S. Constitution in 1789, it has ultimate, and largely discretionary, appellate jurisdiction over all federal courts and state court cases involving issues of U.S. federal law, plus original jurisdiction over a small range of cases. In the legal system of the United States, the Supreme Court is generally the final interpreter of federal law including the U.S. Constitution, but it may act only within the context of a case in which it has jurisdiction. The Court may decide cases having political overtones, but does not have the power to decide political questions that are nonjusticiable, and its enforcement arm is in the executive rather than judicial branch of government. As established by the Judiciary Act of 1869, the Court normally consists of the chief justice of the United States and eight associate justices who are nominated by the president and ...
