Relative quantitation was more reproducible than absolute quantitation and substantial reduction of variance was attained with duplicate spotting.
In addition, the reduction of variance over time using CBF measurements (non-significant) suggests it could potentially provide a more useful approach when assessing longitudinal activation changes.
The reduction of variance in our inversion is about 75%, and the overall fit between observed and calculated data is good.
Calculation of scale factors for the sorption isotherms was successful, as scaling reduction of variance was high (from 64% to 99%).
In the oculomotor model, this reduction of variance leads to a significantly reduced standard deviation of the random error component of saccades (Fig. 4a).
At absolute curvatures of 0.1, the improvement that could still be made can be too small (less than 3% reduction of variance) to be detectable.
We present variance components and reduction of variance to assess the fit of the models.
Reduction of variance has long been recognized as an important feature of learning [75].
SSclim, as defined above, is also known as reduction of variance, because the quotient being subtracted is the average squared error divided by the climatological variance (here estimated by cross-validation).
Following Jensen's inequality [ 18, 39], the reduction of variance in disposable resources makes the formation of egalitarian groups profitable whenever the fitness function (Fig. 1) is upward convex.
