    Here, the first two columns introduce two quantifiers, both of type country, which serve as universal quantifier. In the third column, the 2-ary predicate borders is used to express when two countries have a shared border. Finally, the last column uses the 1-ary function color of, which maps each country on a color.

    Step 5. Propose as a compromise solution the alternative A(1) which is the best ranked by the measure Q (minimum) if the following two conditions are satisfied: C1. “Acceptable Advantage”: Q(A(2) – Q(A(1)) >= DQ where: A(2) is the alternative with second position in the ranking list by Q; DQ = 1/(J-1). C2.

    en.wikipedia.org/wiki/Help:Displaying_a_formula

    Spaces within a formula must be directly managed (for example by including explicit hair or thin spaces). Variable names must be italicized explicitly, and superscripts and subscripts must use an explicit tag or template. Except for short formulas, the source of a formula typically has more markup overhead and can be difficult to read.

  5. Database index - Wikipedia

    en.wikipedia.org/wiki/Database_index

    Some databases can do this, others just won't use the index.

    General references and other full citations may similarly be either combined or separated (e.g. "References" and "General references"). There may therefore be one, two, three or four sections in all. It is most common for only citation footnotes to be used, and therefore it is most common for only one section ("References") to be needed.

    The expected value of perfect information is the difference between these two quantities, EVPI = EV | PI − EMV . {\displaystyle {\mbox{EVPI}}={\mbox{EV}}|{\mbox{PI}}-{\mbox{EMV}}.} This difference describes, in expectation, how much larger a value the player can hope to obtain by knowing j and picking the best i for that j , as compared to ...

    en.wikipedia.org/wiki/Sample_size_determination

    The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4] The parameters used are:
