One characteristic of this model is that the lower level variance (here the hospital) is fixed at exactly 1; this does not affect the interpretation of relative unexplained variance
at each level, but it does preclude making inferences about the absolute magnitude of the unexplained variance
at each level.
In brief, SOLAR incorporates the information contained in participant pedigrees to obtain maximum likelihood estimates for the proportion of unexplained variance
due to additive genetic effects from polygenes ([[delta].
As can be seen from the variance components (Table 3), the total unexplained variance
is 47%, with 18% (32% of total variance) unexplained at the between-person level, and 29% (62% of total variance) at the within-person level.
Since the standard resources of data at our disposal cannot reveal discrimination in the labour market directly, for example, its effects can only be inferred through unexplained variance
in regression models, or other similar approaches.
In truth, the unexplained variance
is due to provider-induced demand, as has been documented by Dartmouth College researchers.
Inclusion of a covariate also improves precision by accounting for the otherwise unexplained variance
associated with the covariate.
Unfortunately, we were unable to perform similar measurements to quantify hyopkinetic walking, which may have accounted for a portion of our unexplained variance
Since 17% of unexplained variance
in actual GPA was found based upon student GPA estimates, the findings support the recommendation that researchers employ the actual GPA recorded in the Registrar's Office whenever possible and feasible.
2], the less error or unexplained variance
and, therefore, the better prediction.
Figure 4, for example, shows us that there are two regions with very high levels of unexplained variance
Although we found significant unexplained variance
in these models, the models did account for a substantial portion of variance evident at the individual level in the unconditional models.
in care was reported to be a major problem by almost one third of survey respondents and sometimes a problem by an additional 61 percent.
