Thus, the explained Level-1 proportion of variation
due to inclusion of both household level and child's characteristics in the model was 11%.
A measure of their adequacy for the user's needs is the proportion of variation
in users' investment decisions explained by these cues.
As with DP, a high proportion of variation
was explained by a relatively simple equation based on the same two variables.
Because MZ twins share 100% of their genes, and DZ twins share, on average, only 50% of their genes, the heritability of IQ (i.e., the proportion of variation
in IQ that is due to genetic factors) can be estimated by doubling the difference between the correlations for MZ and DZ twins.
The proportion of variation
in seed weight that was attributable to site, shrubs, and within-shrub, was remarkably similar to that found in other species.

Wetstein also, in my view, expresses an excessively positivist view of "explanation," equating it with proportion of variation
explained or goodness of (empirical) fit.
The proportion of variation
explained by the lineage or lineage x f effect is very low (Table 1).
[[Beta].sub.1] estimates, indicating the proportion of variation
due to risk premium, are universally positive and reliably different from zero.
Indeed, in the 1980s, the proportion of variation
due to unpredictable structural changes has increased for the effects of wealth on consumption and for the effects of the short-term interest rate on the bond rate and the exchange rate.
