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.
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.
Unfortunately, we were unable to perform similar measurements to quantify hyopkinetic walking, which may have accounted for a portion of our unexplained variance.

Figure 4, for example, shows us that there are two regions with very high levels of unexplained variance (i.
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.
Unexplained variance 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.
Bernhardt's (2000; 2003) most recent L2 reading model includes room for unexplained variance while offering a conceptualization of L2 reading that captures reading over time (see Bernhardt 2000, 803).

Some of the unexplained variance undoubtedly reflects genetic factors, but a portion of the variance is likely due to aspects of the broader social and cultural context that have generally been neglected.
Their prediction equations 6 and 7 decreased unexplained variance from measured GFR by more than one-half when compared with measured creatinine or urea clearance or the Cockcroft-Gault equation, i.
