  2. Uncertainty avoidance - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_avoidance

    In cross-cultural psychology, uncertainty avoidance is how cultures differ on the amount of tolerance they have of unpredictability. [1] Uncertainty avoidance is one of five key qualities or dimensions measured by the researchers who developed the Hofstede model of cultural dimensions to quantify cultural differences across international lines and better understand why some ideas and business ...

  3. Ambiguity aversion - Wikipedia

    en.wikipedia.org/wiki/Ambiguity_aversion

    In decision theory and economics, ambiguity aversion (also known as uncertainty aversion) is a preference for known risks over unknown risks.An ambiguity-averse individual would rather choose an alternative where the probability distribution of the outcomes is known over one where the probabilities are unknown.

  4. Hofstede's cultural dimensions theory - Wikipedia

    en.wikipedia.org/wiki/Hofstede's_cultural...

    Uncertainty avoidance (UAI): The uncertainty avoidance index is defined as "a society's tolerance for ambiguity", in which people embrace or avert an event of something unexpected, unknown, or away from the status quo. Societies that score a high degree in this index opt for stiff codes of behavior, guidelines, laws, and generally rely on ...

  5. Weak formulation - Wikipedia

    en.wikipedia.org/wiki/Weak_formulation

    Weak formulations are important tools for the analysis of mathematical equations that permit the transfer of concepts of linear algebra to solve problems in other fields such as partial differential equations. In a weak formulation, equations or conditions are no longer required to hold absolutely (and this is not even well defined) and has ...

  6. Big Five personality traits - Wikipedia

    en.wikipedia.org/wiki/Big_Five_personality_traits

    Although the relationship was not strong (r=0.32, β=0.28, p<0.01), it was the strongest of the Big Five traits. However, the same study could not predict leadership effectiveness as evaluated by the leader's direct supervisor. [91]

  7. Stochastic differential equation - Wikipedia

    en.wikipedia.org/wiki/Stochastic_differential...

    A weak solution consists of a probability space and a process that satisfies the integral equation, while a strong solution is a process that satisfies the equation and is defined on a given probability space. The Yamada–Watanabe theorem makes a connection between the two. An important example is the equation for geometric Brownian motion

  8. Risk aversion - Wikipedia

    en.wikipedia.org/wiki/Risk_aversion

    This pattern is an indication of risk-seeking behavior in negative prospects and eliminates other explanations for the certainty effect such as aversion for uncertainty or variability. [ 18 ] The initial findings regarding the reflection effect faced criticism regarding its validity, as it was claimed that there are insufficient evidence to ...

  9. Sensitivity analysis - Wikipedia

    en.wikipedia.org/wiki/Sensitivity_analysis

    Taking into account uncertainty arising from different sources, whether in the context of uncertainty analysis or sensitivity analysis (for calculating sensitivity indices), requires multiple samples of the uncertain parameters and, consequently, running the model (evaluating the -function) multiple times. Depending on the complexity of the ...
