    ACH was a step forward in intelligence analysis methodology, but it was first described in relatively informal terms. Producing the best available information from uncertain data remains the goal of researchers, tool-builders, and analysts in industry, academia and government.

  3. Stepwise regression - Wikipedia

    en.wikipedia.org/wiki/Stepwise_regression

    The main approaches for stepwise regression are: Forward selection, which involves starting with no variables in the model, testing the addition of each variable using a chosen model fit criterion, adding the variable (if any) whose inclusion gives the most statistically significant improvement of the fit, and repeating this process until none improves the model to a statistically significant ...

  4. Forward chaining - Wikipedia

    en.wikipedia.org/wiki/Forward_chaining

    Forward chaining (or forward reasoning) is one of the two main methods of reasoning when using an inference engine and can be described logically as repeated application of modus ponens. Forward chaining is a popular implementation strategy for expert systems, business and production rule systems. The opposite of forward chaining is backward ...

    the perfectionist all-or-nothing method, with no attempt at holding partial successes. This would be expected to take more than 10^301 seconds, [i.e., 2^1000 seconds, or 3·5×(10^291) centuries] a serial-test of switches, holding on to the partial successes (assuming that these are manifest), which would take 500 seconds on average

  6. Test statistic - Wikipedia

    en.wikipedia.org/wiki/Test_statistic

    Test statistic is a quantity derived from the sample for statistical hypothesis testing. [1] A hypothesis test is typically specified in terms of a test statistic, considered as a numerical summary of a data-set that reduces the data to one value that can be used to perform the hypothesis test.

    futures (forecasting, forward thinking, prospectives), planning (strategic analysis, priority setting), and; networking (participatory, dialogic) tools and orientations. Much futurology research has been rather ivory tower work, but Foresight programmes were designed to influence policy - often R&D policy. Much technology policy had been very ...

  8. Heuristic - Wikipedia

    en.wikipedia.org/wiki/Heuristic

    Gigerenzer & Gaissmaier (2011) state that sub-sets of strategy include heuristics, regression analysis, and Bayesian inference. [14]A heuristic is a strategy that ignores part of the information, with the goal of making decisions more quickly, frugally, and/or accurately than more complex methods (Gigerenzer and Gaissmaier [2011], p. 454; see also Todd et al. [2012], p. 7).

    The AUT measures a certain level of divergent thinking; exploring multiple answers using creativity [1] It doesn't compare to a traditional test that looks for a specific solution. [citation needed] As a result, from the AUT it is measured in four ways: [citation needed] Fluency: the number of other uses you can think of, from the original object
