In computer science, the count-distinct problem [1] (also known in applied mathematics as the cardinality estimation problem) is the problem of finding the number of distinct elements in a data stream with repeated elements. This is a well-known problem with numerous applications.

Presumably from the practice, in counting sheep or large herds of cattle, of counting orally from one to twenty, and making a score or notch on a stick, before proceeding to count the next twenty.

In descriptive statistics, the range of a set of data is size of the narrowest interval which contains all the data. It is calculated as the difference between the largest and smallest values (also known as the sample maximum and minimum). [1] It is expressed in the same units as the data. The range provides an indication of statistical ...
The Oracle Database SYS_GUID function does not return a standard GUID, despite the name. Instead, it returns a 16-byte 128-bit RAW value based on a host identifier and a process or thread identifier, somewhat similar to a GUID. [34] PostgreSQL contains a UUID datatype [35] and can generate most versions of UUIDs through the use of functions ...
Fitting of a noisy curve by an asymmetrical peak model, with an iterative process (Gauss–Newton algorithm with variable damping factor α).Curve fitting [1] [2] is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, [3] possibly subject to constraints.
Range of a function, a set containing the output values produced by a function Range (statistics) , the difference between the highest and the lowest values in a set Interval (mathematics) , also called range , a set of real numbers that includes all numbers between any two numbers in the set
The codespace is a systematic, architecture-independent representation of The Unicode Standard; actual text is processed as binary data via one of several Unicode encodings, such as UTF-8. In this normative notation, the two-character prefix U+ always precedes a written code point, [63] and the code points themselves are written as hexadecimal ...
