Draft:Influence relationship

Influence relationship is defined as a directional relationship in the category of correlation.[1][2] For example, the environment influences emotion, the child's age influences athletic ability, and childhood trauma influences adolescent adjustment. The variable that appears earlier is called the influence factor and the variable that emerges later is the outcome.

Correlation is covariation between variables, reflecting the association between variables. Directionality is a sequential order between variables, reflecting the effect of one variable on another.[3] Relationships between variables in many statistical models (e.g., mediated effects, moderated effects models) usually satisfy both, the arrow between variables based on well-founded assumptions (directionality), and the statistical significance of the coefficients of the paths between variables (covariation).

The associations among influence, correlation, and causation are shown in Figure 1. Causation must be influence while influence must be correlation. In terms of extension, the three types of relationships are inclusive, with correlation encompassing influence and influence encompassing causation. The connotations of the three are just the opposite, with correlation having the least connotations and causation having the most.

In the fields of epidemiology and clinical psychology, the concept of risk factor[4] is often mentioned. Risk factors are all influence factors, but the relationship between risk factors and outcomes is not necessarily causal. The opposite of risk factors is protective factors, which can simply be understood as influences that reduce the occurrence of negative outcomes. That is, both risk factors and protective factors are influences on negative outcomes, and negative outcomes will increase as the level of risk factors rises and decrease as the level of protective factors drops.

Influence relationship is established according to two criteria, directionality and correlation. Statistical analyses of influence relationship include the commonly used test of variance, correlation analysis, regression analysis, and path analysis, depending on the type of variables and the number of influence factors.

The key to modeling influence relationships is to find evidence for directionality. The following approaches can be used to find evidence for determining the termporal order of variables: (1) determining the direction based on the chronological order of variable occurrences; (2) reversing the termporal order of two variables to see which one is easier to explain; (3) following the rule that object variables influence subject variables; (4) determining according to attributes of variables, i.e., essential attributes may influence state attributes, long-term attributes impact temporary attributes, and stable attributes affect unstable attributes; (5) gaining support from theories or empirical literature; (6) summarizing from life experience and common sense; (7) reasoning through analogies; (8) using the principles of cross-lag analysis to identify dominant factors.
