    en.wikipedia.org/wiki/Fraction

    A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a / b or ⁠ ⁠, where a and b are both integers. [ 9] As with other fractions, the denominator ( b) cannot be zero. Examples include ⁠ 1 2 ⁠, − ⁠ 8 5 ⁠, ⁠ −8 5 ⁠, and ⁠ 8 −5 ⁠.

  3. Mixed-member proportional representation - Wikipedia

    en.wikipedia.org/wiki/Mixed-member_proportional...

    e. Mixed-member proportional representation ( MMP or MMPR) is a mixed electoral system which combines local winner-take-all elections with a compensatory tier of party list votes, which are used to allocate additional members in a way that aims to produce proportional representation overall. In typical MMP systems, voters get two votes: one to ...

  4. Mixed electoral system - Wikipedia

    en.wikipedia.org/wiki/Mixed_electoral_system

    A mixed electoral system or mixed-member electoral system combines methods of majoritarian and proportional representation (PR). [ 1][ 2][ 3] The majoritarian component is usually first-past-the-post voting (FPTP/SMP), [ 4] whereas the proportional component is most often based on party-list PR. The results of the combination may be mixed ...

  5. Continuous or discrete variable - Wikipedia

    en.wikipedia.org/wiki/Continuous_or_discrete...

    An example of a mixed model could be a research study on the risk of psychological disorders based on one binary measure of psychiatric symptoms and one continuous measure of cognitive performance. [15] Mixed models may also involve a single variable that is discrete over some range of the number line and continuous at another range.

  6. Nash equilibrium - Wikipedia

    en.wikipedia.org/wiki/Nash_equilibrium

    The free money game is an example of a "special" game with an even number of equilibria. In it, two players have to both vote "yes" rather than "no" to get a reward and the votes are simultaneous. There are two pure-strategy Nash equilibria, (yes, yes) and (no, no), and no mixed strategy equilibria, because the strategy "yes" weakly dominates "no".

    This means, the number of seats effectively assigned proportionally based on the parallel party list votes is unknown/unknowable before the election takes place. [5] Before the 2014, a different mixed system was used with a two-round system in single-member districts. Italy: Chamber of Deputies: 2018: Superposition

    The relative effect of buoyancy on mixed convection can be expressed through the Richardson number: R i = G r R e 2 {\displaystyle \mathrm {Ri} ={\frac {\mathrm {Gr} }{\mathrm {Re} ^{2}}}} The respective length scales for each dimensionless number must be chosen depending on the problem, e.g. a vertical length for the Grashof number and a ...

  9. Mixed model - Wikipedia

    en.wikipedia.org/wiki/Mixed_model

    A mixed model, mixed-effects model or mixed error-component model is a statistical model containing both fixed effects and random effects. [ 1][ 2] These models are useful in a wide variety of disciplines in the physical, biological and social sciences. They are particularly useful in settings where repeated measurements are made on the same ...
