This suggests that the highly powerful explanatory effect of MKT in the single-factor model may largely result from covariation
between th e overall stock market factor and other factors.
A major focus is to investigate whether there is a genetic influence on the covariation
among measures of these two basic abilities that accounts for a significant part of the genetic variance in intelligence.
But as measured empirically, the contemporaneous, quarter-by-quarter covariation
of consumption with the stock market is low.
Previous studies showed that the cluster and accumulation of risk behaviors, where several patterns of behavior occur simultaneously more often than one would expect on the basis of probability, is pronounced.[6-9] Furthermore, the evidence for covariation
has been strongest for those risk behaviors that are also problem behaviors, such as drug use, alcohol abuse, delinquency, and sexual precocity.
But the question remains whether there is still systematic covariation
in the unexplained remainder of bequests to spouses, relatives, servants and religious institutions.
between the network and its generators at each moment in time is expected to develop into a coevolution over time at the interface because of the recursivity of the selective condition.(d) In other words, evolutionary systems follow and produce their histories in terms of coevolutionary trajectories.
Because FFS patients were more likely to be African American, observed differences by race may be because of the covariation
of race with insurer type.
Under LSA, we specify plausible or hypothesized levels of uncertainty, variation, and covariation
in vital rates for a given population.
Next we performed a series of structural equation models to determine the pattern of relationships among the computer-related latent constructs, age, and education that would most parsimoniously reproduce the pattern of covariation
in the measurement model.
employees, job distress and family distress have a significant positive non-causal covariation
. However, among Hong Kong employees, job satisfaction and family satisfaction do not have significant covariation
Judgments of covariation
are of interest in different domains of psychology including cognitive development (e.g.
Removal of the effects of covariation
and interaction clearly indicates that decentralized programs result in poorer performance than a centralized program.
