Interaction effect of education and ideology on concern about sea level rise. In statistics, an interaction may arise when considering the relationship among three or more variables, and describes a situation in which the effect of one causal variable on an outcome depends on the state of a second causal variable (that is, when effects of the two causes are not additive).
The interaction information is represented by gray region, and it is the only one that can be negative. In probability theory and information theory , the interaction information is a generalization of the mutual information for more than two variables .
Interaction hypothesis, a theory of second language acquisition; Interaction (statistics), when three or more variables influence each other; Interactions of actors theory, created by cybernetician Gordon Pask; Fundamental interaction or fundamental force, the core interactions in physics; Human–computer interaction, interfaces for people ...
Other measures of association include Pearson's chi-squared test statistics, G-test statistics, etc. In fact, with the same log base, mutual information will be equal to the G-test log-likelihood statistic divided by 2 N {\displaystyle 2N} , where N {\displaystyle N} is the sample size.
[1] [2] The effect of a moderating variable is characterized statistically as an interaction; [1] that is, a categorical (e.g., sex, ethnicity, class) or continuous (e.g., age, level of reward) variable that is associated with the direction and/or magnitude of the relation between dependent and independent variables.
Affordability is becoming a growing challenge for younger generations. Although they're often drawn to vibrant cities for their career opportunities and lifestyle perks, high housing costs make ...
Simple mediation model. The independent variable causes the mediator variable; the mediator variable causes the dependent variable. In statistics, a mediation model seeks to identify and explain the mechanism or process that underlies an observed relationship between an independent variable and a dependent variable via the inclusion of a third hypothetical variable, known as a mediator ...
Angelina Jolie laughed when a reporter asked her what a biopic of her life might look like and said in part, "Let’s hope there isn’t one about my life"
