A surname, family name, or last name is the portion of a personal name that indicates a person's family. Depending on the culture, all members of a family unit may have identical surnames or there may be variations based on the cultural rules.
In probability theory and statistics, the zeta distribution is a discrete probability distribution. If X is a zeta-distributed random variable with parameter s, then the probability that X takes the integer value k is given by the probability mass function
In probability theory and statistics, the Zipf–Mandelbrot law is a discrete probability distribution. Also known as the Pareto-Zipf law, it is a power-law distribution on ranked data, named after the linguist George Kingsley Zipf who suggested a simpler distribution called Zipf's law, and the mathematician Benoit Mandelbrot, who subsequently generalized it.
The year 1935 in science and technology involved some significant events, listed below.
Gibrat's law is a rule defined by Robert Gibrat (1904–1980) in 1931 stating that the proportional rate of growth of a firm is independent of its absolute size. The law of proportionate growth gives rise to a distribution that is log-normal.
In the Philippines, varying naming customs are observed, whether it is given name first, family name last, a mixture of native conventions with those of neighbouring territories, etc. The most common iteration amongst Filipinos is a blend of the older Spanish system and Anglo-American conventions, where there is a distinction between the "Christian name" from "surname". The construct of having several names in the middle name convention is common to all systems, but to have multiple "first" names and only one middle and last name is a result of the blending of American and Spanish naming customs. The Tagalog language is one of the few national languages in Asia to use the Western name order while formally uses the eastern name order. Thus, the Philippine naming custom is coincidentally identical to the Spanish and Portuguese name customs and to an extent Chinese naming customs.
Lehesten is a town in the Thuringian Forest, 20 km southeast of Saalfeld.
An empirical statistical law or a law of statistics represents a type of behaviour that has been found across a number of datasets and, indeed, across a range of types of data sets. Many of these observances have been formulated and proved as statistical or probabilistic theorems and the term "law" has been carried over to these theorems. There are other statistical and probabilistic theorems that also have "law" as a part of their names that have not obviously derived from empirical observations. However, both types of "law" may be considered instances of a scientific law in the field of statistics. What distinguishes an empirical statistical law from a formal statistical theorem is the way these patterns simply appear in natural distributions, without a prior theoretical reasoning about the data.
In the field of ecology, the relative abundance distribution (RAD) or species abundance distribution describes the relationship between the number of species observed in a field study as a function of their observed abundance. The graphs obtained in this manner are typically fitted to a Zipf–Mandelbrot law, the exponent of which serves as an index of biodiversity in the ecosystem under study.
