Marginal

from Wikipedia, the free encyclopedia

A marginal ( Latin margo , marginis = "edge") is something that is on the edge / on the border, incidental (that is, on the edge of a thing , i.e. something on the edge of a subject area). The word does not have to have a devaluing connotation , but this can certainly resonate. Another important group of meanings relates from the limit value methodology ( infinitesimal calculus ) to mathematically derived quantities, especially in economics.

Lying just outside the edge of an object area:

  • The word marginal is also used adjectivally ( these problems are marginal (= incidental) so that they should not be mentioned - or: this is of marginal (= incidental) importance ).
  • Marginal counterexamples : If you want to clarify for a predicator , i.e. for a linguistic expression that is representative for certain objects or object classes, to which object area it relates, you can achieve this via so-called object anchoring. In doing so, one shows examples that are as representative as possible , for which the predicator stands, and counter-examples that are as marginal as possible , for which the predicator does not. The more marginal, i.e. the closer to the boundary to the object area of ​​interest, the counterexample, the more precisely this boundary can be determined. Objects that are just outside the boundary of the object area for which the predicator stands can thus be safely excluded as not belonging to the predicator.
Example: If you point to the color turquoise (rectangle D) and say “This is not green”, turquoise serves as a marginal counterexample for the predicator green. The counter-example turquoise is marginal because the color turquoise falls almost, but not entirely, into the green object area, i.e. turquoise is just outside the edge of the green object area. The color blue (rectangle G) would not be a marginal counterexample here because it is quite far from the edge of the object area. The subject area green could not be narrowed enough with this counterexample and the delimitation would remain vague or the subject area would be defined too large.

Use as spatial information:

  • Marginal probability is a rarely used synonym for the term marginal probability . The marginal probability refers to the probabilities that are at the edge of a frequency table that contains the relative frequencies for combinations of characteristics ( contingency table ). About the relative frequency at the edge of the table ( marginal rate , marginal rate , the marginal probability is estimated edge frequency). For example, the probability of being male in this sample can be read from the relative marginal frequency and is 0.35 in this example. All marginal frequencies across a feature, together form the so-called marginal distribution ( marginal distribution )
man woman Marginal probability
grade 10 0.25 0.25 0.50
11th grade 0.10 0.40 0.50
Marginal probability 0.35 0.65 1.00
  • In dentistry , marginal means "belonging to the gumline".

In the sense of small:

  • In economics, a marginal change in quantity means a change by the smallest possible unit. The concept of marginality is important, for example, for determining marginal utility . A focus on looking at small changes in status sparked the marginalist revolution in economics.

Language:

  • In Finnish there is the marginal case. Here is an excerpt from the Finnish language page on the topic of marginal cases:
