  2. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    An important question in terms of dynamical systems is how the behavior of the trajectory changes when the parameter r changes. Depending on the value of r, the behavior of the trajectory of the logistic map can be simple or complex. [Thompson & Stewart 1] Below, we will explain how the behavior of the logistic map changes as r increases.

  3. Cobweb plot - Wikipedia

    en.wikipedia.org/wiki/Cobweb_plot

    An animated cobweb diagram of the logistic map = (), showing chaotic behaviour for most values of >. A cobweb plot , known also as Lémeray Diagram or Verhulst diagram is a visual tool used in the dynamical systems field of mathematics to investigate the qualitative behaviour of one-dimensional iterated functions , such as the logistic map .

  4. Control chart - Wikipedia

    en.wikipedia.org/wiki/Control_chart

    Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.

  5. Formal concept analysis - Wikipedia

    en.wikipedia.org/wiki/Formal_concept_analysis

    The above line diagram consists of circles, connecting line segments, and labels. Circles represent formal concepts. The lines allow to read off the subconcept-superconcept hierarchy. Each object and attribute name is used as a label exactly once in the diagram, with objects below and attributes above concept circles.

  6. Argument map - Wikipedia

    en.wikipedia.org/wiki/Argument_map

    Each of these structures can be represented by the equivalent "box and line" approach to argument maps. In the following diagram, the contention is shown at the top, and the boxes linked to it represent supporting reasons, which comprise one or more premises. The green arrow indicates that the two reasons support the contention: A box and line ...

  7. Theory of basic human values - Wikipedia

    en.wikipedia.org/wiki/Theory_of_basic_human_values

    One of the main limitations of this theory lies in the methodology of the research. The SVS is comparatively difficult to answer, because respondents have to first read the set of 30 value items and give one value the highest as well as the lowest ranking (0 or −1, depending on whether an item is opposed to their values).

  8. Threshold model - Wikipedia

    en.wikipedia.org/wiki/Threshold_model

    A threshold model used in toxicology posits that anything above a certain dose of a toxin is dangerous, and anything below it safe. This model is usually applied to non-carcinogenic health hazards. Edward J. Calabrese and Linda A. Baldwin wrote: The threshold dose-response model is widely viewed as the most dominant model in toxicology. [6]

  9. Economic surplus - Wikipedia

    en.wikipedia.org/wiki/Economic_surplus

    In Figure 1, the shaded areas below the price line and above the supply curve between production zero and maximum output Q 1 indicate producer surplus. Among them, OP 1 EQ 1 below the price line. This indicates that the total revenue is the minimum total payment actually accepted by the manufacturer. The area OP M EQ 1 below the S curve is the ...
