Ordination or gradient analysis, in multivariate analysis, is a method complementary to data clustering, and used mainly in exploratory data analysis (rather than in hypothesis testing). In contrast to cluster analysis, ordination orders quantities in a (usually lower-dimensional) latent space. In the ordination space, quantities that are near each other share attributes (i.e., are similar to some degree), and dissimilar objects are farther from each other. Such relationships between the objects, on each of several axes or latent variables, are then characterized numerically and/or graphically in a biplot.

Ordination methods can broadly be categorized in eigenvector-, algorithm-, or model-based methods. Many classical ordination techniques, including principal components analysis, correspondence analysis (CA) and its derivatives (detrended correspondence analysis, canonical correspondence analysis, and redundancy analysis, belong to the first group.

The third group includes model-based ordination methods, which can be considered as multivariate extensions of Generalized Linear Models.[1][2][3][4] Model-based ordination methods are more flexible in their application than classical ordination methods, so that it is for example possible to include random-effects.[5] Unlike in the aforementioned two groups, there is no (implicit or explicit) distance measure in the ordination. Instead, a distribution needs to be specified for the responses as is typical for statistical models. These and other assumptions, such as the assumed mean-variance relationship, can be validated with the use of residual diagnostics, unlike in other ordination methods.

Ordination is the process by which individuals are consecrated, that is, set apart and elevated from the laity class to the clergy, who are thus then authorized (usually by the denominational hierarchy composed of other clergy) to perform various religious rites and ceremonies.[1] The process and ceremonies of ordination vary by religion and denomination. One who is in preparation for, or who is undergoing the process of ordination is sometimes called an ordinand. The liturgy used at an ordination is sometimes referred to as an ordination.

There are three "degrees" of ordination (or holy orders): deacon, presbyter, and bishop. Both bishops and presbyters are priests and have authority to celebrate the Eucharist. In common use, however, the term priest, when unqualified, refers to the rank of presbyter, whereas presbyter is mainly used in rites of ordination and other places where a technical and precise term is required.

Ordination of a bishop is performed by several bishops; ordination of a priest or deacon is performed by a single bishop. The ordination of a new bishop is also called a consecration. Many ancient sources specify that at least three bishops are necessary to consecrate another, e.g., the 13th Canon of the Council of Carthage (AD 394) states, "A bishop should not be ordained except by many bishops, but if there should be necessity he may be ordained by three,"[5] and the first of "The Canons of the Holy and Altogether August Apostles" states, "Let a bishop be ordained by two or three bishops," while the second canon thereof states, "Let a presbyter, deacon, and the rest of the clergy, be ordained by one bishop";[6] the latter canons, whatever their origin, were imposed on the universal church by the Seventh Ecumenical Council, the Second Council of Nicaea, in its first canon.[7]

The Catholic Church teaches that one bishop is sufficient to consecrate a new bishop validly (that is, for an episcopal ordination actually to take place). In most Christian denominations that retain the practice of ordination, only an already ordained (consecrated) bishop or the equivalent may ordain bishops, priests, and deacons.[8] However, Canon Law requires that bishops always be consecrated with the mandate (approval) of the Roman Pontiff, as the guarantor of the Church's unity.[9] Moreover, at least three bishops are to perform the consecration, although the Apostolic See may dispense from this requirement in extraordinary circumstances (for example, in missionary settings or times of persecution).[10]

In the Roman Catholic Church, those deacons destined to be ordained priests are often termed transitional deacons; those deacons who are married before being ordained, as well as any unmarried deacons who chose not to be ordained priests, are called permanent deacons. Those married deacons who become widowers have the possibility of seeking ordination to the priesthood in exceptional cases.[11]

Some Eastern Orthodox churches recognize Roman Catholic ordinations while others "re-ordain" Roman Catholic clergy (as well as Anglicans) who convert. However, both the Roman Catholic and Anglican churches recognize Orthodox ordinations.

In the Roman Catholic and Anglican churches, ordinations have traditionally been held on Ember Days, though there is no limit to the number of clergy who may be ordained at the same service. In the Eastern Orthodox Church, ordinations may be performed any day of the year on which the Divine Liturgy may be celebrated (and deacons may also be ordained at the Presanctified Liturgy), but only one person may be ordained to each rank at any given service, that is, at most one bishop, one presbyter, and one deacon may be ordained at the same liturgy.[17]

For most Protestant denominations that have an office of bishop, including certain Lutheran and many Methodist churches, this is not viewed as a separate ordination or order of ministry. Rather, bishops are ordained ministers of the same order as other pastors, simply having been "consecrated" or installed into the "office" (that is, the role) of bishop. However, some Lutheran churches also claim valid apostolic succession.[21]

Jehovah's Witnesses consider an adherent's baptism to constitute ordination as a minister.[25] Governments have generally recognized that Jehovah's Witnesses' full-time appointees (such as their "regular pioneers") qualify as ministers[26] regardless of sex or appointment as an elder or deacon ("ministerial servant"). The religion asserts ecclesiastical privilege only for its appointed elders,[27][28] but the religion permits any baptized adult male in good standing to officiate at a baptism, wedding, or funeral.[29]

While the Hebrew word semikhah is rendered as "ordination" in English, a rabbi is not a priest per se, but primarily functions as a legal scholar and teacher of Torah; and in fact, for many religious purposes the presence of a rabbi is not necessary. (For example, at prayer, a minyan (quorum) of ten lay-people is both necessary and sufficient; thus the saying "nine rabbis do not constitute a minyan, but ten cobblers can".[32])

Recently, in some denominations, Semikhah, or semicha lehazzanut, may refer to the ordination of a hazzan (cantor);while others use the term "investiture" to describe the conferral of cantorial authority.

The tradition of the ordained monastic community (sangha) began with the Buddha, who established orders of monks and later of nuns. The procedure of ordination in Buddhism is laid down in the Vinaya and Patimokkha or Pratimoksha scriptures. There exist three intact ordination lineages nowadays in which one can receive an ordination according to the Buddha's teachings:[citation needed]

Saicho repeatedly requested that the Japanese government allow the construction of a Mahayana ordination platform. Permission was granted in 822 CE, seven days after Saicho died. The platform was finished in 827 CE at Enryaku-ji temple on Mount Hiei, and was the first in Japan. Prior to this, those wishing to become monks/nuns were ordained using the Hinayana precepts, whereas after the Mahayana ordination platform, people were ordained with the Bodhisattva precepts as listed in the Brahma Net Sutra.[33]

The Buddhist ordination tradition of the New Kadampa Tradition-International Kadampa Buddhist Union (NKT-IKBU) is not the traditional Buddhist ordination, but rather one newly created by Kelsang Gyatso. Although those ordained within this organisation are called 'monks' and 'nuns' within the organisation, and wear the robes of traditional Tibetan monks and nuns, in terms of traditional Buddhism they are neither fully ordained monks and nuns (Skt.: bhikshu, bhikshuni; Tib.: gelong, gelongma) nor are they novice monks and nuns (Skt.: sramanera, srameneri; Tib.: gestul, getsulma).[37][38][39]

Kelsang Gyatso's ordination has been publicly criticised by Geshe Tashi Tsering as going against the core teachings of Buddhism and against the teachings of Tsongkhapa, the founder of the Gelugpa school from which Kelsang Gyatso was expelled[41][42][43]

As Unitarian Universalism features very few doctrinal thresholds for prospective congregation members, ordinations of UU ministers are considerably less focused upon doctrinal adherence than upon factors such as possessing a Masters of Divinity degree from an accredited higher institution of education and an ability to articulate an understanding of ethics, spirituality and humanity.

In the Unitarian Universalist Association, candidates for "ministerial fellowship" with the denomination (usually third-year divinity school students) are reviewed, interviewed, and approved (or rejected) by the UUA Ministerial Fellowship Committee (MFC). However, given the fundamental principle of congregational polity, individual UU congregations make their own determination on ordination of ministers, and congregations may sometimes even hire or ordain persons who have not received UUA ministerial fellowship, and may or may not serve the congregation as its principle minister/pastor.

The ordination of women is often a controversial issue in religions where either the office of ordination, or the role that an ordained person fulfills, is traditionally restricted to men, for various theological reasons. 041b061a72
