  2. Elimination theory - Wikipedia

    en.wikipedia.org/wiki/Elimination_theory

    The field of elimination theory was motivated by the need of methods for solving systems of polynomial equations.. One of the first results was Bézout's theorem, which bounds the number of solutions (in the case of two polynomials in two variables at Bézout time).

  3. Log-linear analysis - Wikipedia

    en.wikipedia.org/wiki/Log-linear_analysis

    Violations to this assumption result in a large reduction in power. Suggested solutions to this violation are: delete a variable, combine levels of one variable (e.g., put males and females together), or collect more data. 3. The logarithm of the expected value of the response variable is a linear combination of the explanatory variables.

  4. Heuristic (psychology) - Wikipedia

    Elimination by aspects could be used when facing selections. In general, the process of elimination by aspects is as follows: Step 1: Select one attribute related to decision making; Step 2: Eliminate all alternatives that exclude this specific attribute; Step 3: Use another attribute in order to further eliminate alternatives

  5. Between-group design experiment - Wikipedia

    en.wikipedia.org/wiki/Between-group_design...

    The utilization of the between-group experimental design has several advantages. First, multiple variables, or multiple levels of a variable, can be tested simultaneously, and with enough testing subjects, a large number can be tested. Thus, the inquiry is broadened and extended beyond the effect of one variable (as with within-subject design).

  6. Design of experiments - Wikipedia

    The same is true for intervening variables (a variable in between the supposed cause (X) and the effect (Y)), and anteceding variables (a variable prior to the supposed cause (X) that is the true cause). When a third variable is involved and has not been controlled for, the relation is said to be a zero order relationship. In most practical ...

    Comparing the factors known about the countries above, a comparative political scientist would conclude that the government sitting on the centre-left of the spectrum would be the independent variable which causes a system of universal health care, since it is the only one of the factors examined which holds constant between the two countries ...

  8. Process of elimination - Wikipedia

    en.wikipedia.org/wiki/Process_of_elimination

    Process of elimination is a logical method to identify an entity of interest among several ones by excluding all other entities. In educational testing , it is a process of deleting options whereby the possibility of an option being correct is close to zero or significantly lower compared to other options.

  9. Josephus problem - Wikipedia

    The details of the mechanism used in this feat are rather vague. According to James Dowdy and Michael Mays, [2] in 1612 Claude Gaspard Bachet de Méziriac suggested the specific mechanism of arranging the men in a circle and counting by threes to determine the order of elimination. [3]
