This method maximizes the variance between classes and reduces the variance within classes.
The drawbacks include further loss of data, biasing the sample statistics, and reducing the variance of the variable in question (Acock, 2005; Little & Rubin, 2002; Peugh & Enders, 2004; Rubin, 1987).
Signature expansion, combining two images acquired during different seasons from the same year, often improved classification accuracy and reduced the variance in accuracy compared with conventional single-image classification.
Using platelet-depleted plasma substantially decreases blood cell-associated miRNAs, preserves relevant species in circulation, and reduces the variance in expression levels [ 19].
As implied above, corrections for measurement error made after, rather than before, averaging in meta-analyses, may exaggerate sampling error variance and reduces the variance of the estimated correlation.
It has been proposed that miRNAs exert their effect by setting the mean and reducing the variance of the genes that they regulate, and in this way, they stabilize phenotypes a process called canalization (Wu et al. 2009).
The benefits of increasing corridor width occur because, even if individuals cannot disperse between patches within a single generation, a wide corridor facilitates higher absolute population sizes in the surrounding area, encouraging the exchange of individuals across a broader area, and reducing the variance in reproductive success and subsequent genetic drift (Christie et al. 2012).
But using one constant per destination country may more accurately explain the effects specific to the destination country that influence the imports and thus reduce the variance of the error terms ε.
We model the retailer's risk aversion primarily in the mean variance framework and find that the rebate program can be designed to increase the mean profit and reduce the profit variance simultaneously.
We divide the exposed (E), infectious (I) and sero-converting (C) classes into 5, 5 and 10 compartments respectively to reduce the variance of the time spent in each compartment [ 23].
