Theil Index
The Theil index is a statistic primarily used to measure economic inequality and other economic phenomena, though it has also been used to measure racial segregation. The Theil index ''T''T is the same as redundancy in information theory which is the maximum possible entropy of the data minus the observed entropy. It is a special case of the generalized entropy index. It can be viewed as a measure of redundancy, lack of diversity, isolation, segregation, inequality, non-randomness, and compressibility. It was proposed by a Dutch econometrician Henri Theil (1924-2000) at the Erasmus University Rotterdam. Henri Theil himself said (1967): "The (Theil) index can be interpreted as the expected information content of the indirect message which transforms the population shares as prior probabilities into the income shares as posterior probabilities." Amartya Sen noted, "But the fact remains that the Theil index is an arbitrary formula, and the average of the logarithms of the reciprocal ...

Theil–Sen Estimator
In non-parametric statistics, the Theil–Sen estimator is a method for robustly fitting a line to sample points in the plane (simple linear regression) by choosing the median of the slopes of all lines through pairs of points. It has also been called Sen's slope estimator, slope selection, the single median method, the Kendall robust line-fit method, and the Kendall–Theil robust line. It is named after Henri Theil and Pranab K. Sen, who published papers on this method in 1950 and 1968 respectively,; and after Maurice Kendall because of its relation to the Kendall tau rank correlation coefficient. This estimator can be computed efficiently, and is insensitive to outliers. It can be significantly more accurate than non-robust simple linear regression (least squares) for skewed and heteroskedastic data, and competes well against least squares even for normally distributed data in terms of statistical power. It has been called "the most popular nonparametric technique for es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Theil
Henri (Hans) Theil (October 13, 1924 – August 20, 2000) was a Dutch econometrician and professor at the Netherlands School of Economics in Rotterdam, known for his contributions to the field of econometrics. Biography Born in Amsterdam, Theil started to study mathematics and physics at Utrecht University in 1942. Later in World War II he was arrested and was imprisoned in Vught. After the war he started to study economics at the Gemeente-Universiteit Amsterdam, where in 1951 he received his PhD under Pieter Hennipman.Raj, Baldev.

Erster Theil Etlicher Choräle
''Erster Theil etlicher Choräle'' (commonly known as ''Acht Choräle zum Präambulieren'', PWC 45–52, T. 1–8, PC 1–8) is a collection of liturgical organ music by Johann Pachelbel, published during his lifetime. It contains eight chorale preludes in seven different styles. General information ''Erster Theil etlicher Choräle'' (literally "First Part of collection ofassorted chorales") is one of Pachelbel's earliest publications. It is a mystery, however, when or where it was first published. Johann Mattheson mentions that the first edition appeared before 1693, while the edition lacked any indications of the year of publication. The only copy extant today is a Nuremberg edition by Johann Christoph Weigel, who also published Pachelbel's ''Hexachordum Apollinis'' (1699) and a reprint of his ''Musicalische Ergötzung''. This copy is marked "1693", however, there are two problems with this date. The first is that it was added by another hand at a later date, the second is th ...

Uncertainty Coefficient
In statistics, the uncertainty coefficient, also called proficiency, entropy coefficient or Theil's U, is a measure of nominal association. It was first introduced by Henri Theil and is based on the concept of information entropy. Definition Suppose we have samples of two discrete random variables, ''X'' and ''Y''. By constructing the joint distribution, , from which we can calculate the conditional distributions, and , and calculating the various entropies, we can determine the degree of association between the two variables. The entropy of a single distribution is given as: : H(X)= -\sum_x P_X(x) \log P_X(x) , while the conditional entropy is given as: : H(X, Y) = -\sum_ P_(x,~y) \log P_(x, y) . The uncertainty coefficient or proficiency is defined as: : U(X, Y) = \frac = \frac , and tells us: given ''Y'', what fraction of the bits of ''X'' can we predict? In this case we can think of ''X'' as containing the total information, and of ''Y'' as allowing one to pred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thiel (other)
Thiele/Small parameters (commonly abbreviated T/S parameters, or TSP) are a set of electromechanical parameters that define the specified low frequency performance of a loudspeaker driver. These parameters are published in specification sheets by driver manufacturers so that designers have a guide in selecting off-the-shelf drivers for loudspeaker designs. Using these parameters, a loudspeaker designer may simulate the position, velocity and acceleration of the diaphragm, the input impedance and the sound output of a system comprising a loudspeaker and enclosure. Many of the parameters are strictly defined only at the resonant frequency, but the approach is generally applicable in the frequency range where the diaphragm motion is largely pistonic, i.e. when the entire cone moves in and out as a unit without cone breakup. Rather than purchase off-the-shelf components, loudspeaker design engineers often define desired performance and work backwards to a set of parameters and manufactur ...

German-language Surnames
German ( ) is a West Germanic language mainly spoken in Central Europe. It is the most widely spoken and official or co-official language in Germany, Austria, Switzerland, Liechtenstein, and the Italian province of South Tyrol. It is also a co-official language of Luxembourg and Belgium, as well as a national language in Namibia. Outside Germany, it is also spoken by German communities in France (Bas-Rhin), Czech Republic (North Bohemia), Poland (Upper Silesia), Slovakia (Bratislava Region), and Hungary (Sopron). German is most similar to other languages within the West Germanic language branch, including Afrikaans, Dutch, English, the Frisian languages, Low German, Luxembourgish, Scots, and Yiddish. It also contains close similarities in vocabulary to some languages in the North Germanic group, such as Danish, Norwegian, and Swedish. German is the second most widely spoken Germanic language after English, which is also a West Germanic language. German is one of the major ...
