The graph of a probability mass function. All the values of this function must be non-negative and sum up to 1. In probability and statistics, a probability mass function (sometimes called probability function or frequency function [1]) is a function that gives the probability that a discrete random variable is exactly equal to some value.

Primary myelofibrosis (PMF) is a rare bone marrow blood cancer. [1] It is classified by the World Health Organization (WHO) as a type of myeloproliferative neoplasm, a group of cancers in which there is activation and growth of mutated cells in the bone marrow. This is most often associated with a somatic mutation in the JAK2, CALR, or MPL genes.
PMF may stand for: Danish Union of Educators (Danish: Pædagogisk Medhjælper Forbund), a former Danish trade union; Pacific Music Festival, an international classical music festival held annually in Sapporo, Japan; Paramilitary forces, a semi-militarized force
The development of PMF is usually associated with a restrictive ventilatory defect on pulmonary function testing. PMF can be mistaken for bronchogenic carcinoma and vice versa. PMF lesions tend to grow very slowly, so any rapid changes in size, or development of cavitation, should prompt a search for either alternative cause or secondary disease.
The Presidential Management Fellows (PMF) [1] Program is a two-year training and leadership development program at a United States government agency, administered by the U.S. Office of Personnel Management (OPM), for advanced degree holders (both current and recent graduates). After completing the program, agencies may convert PMFs to permanent ...
The facilities were used by PMF forces combatting ISIL in collaboration with the Iraqi and Syrian governments. U.S. officials described the PMF as an "Iranian-backed militia" and the air strike as a retaliation for purported Iranian military aggression against U.S. facilities in Iraq, while Iranian officials denied involvement.
Prefibrotic primary myelofibrosis (Pre-PMF) is a rare blood cancer, classified by the World Health Organization as a distinct type of myeloproliferative neoplasm in 2016. [1] The disease is progressive to overt primary myelofibrosis , though the rate of progression is variable and not all patients progress.
However, this use is not standard among probabilists and statisticians. In other sources, "probability distribution function" may be used when the probability distribution is defined as a function over general sets of values or it may refer to the cumulative distribution function, or it may be a probability mass function (PMF) rather than the ...
