Among Abowd's most influential articles was " High Wage Workers and High Wage Firms ", in which Abowd, Francis Kramarz, and David Margolis used a matched sample of French employees and employers to decompose annual compensation into components related to observable employee characteristics, personal heterogeneity, firm heterogeneity, and residual variation.

Wexler et al . use these methods in a sample of about 4, 000 Huntington s disease ( HD ) patients from one of the world s best characterized populations in Venezuela to estimate that about 40 % of residual variation in age of onset is attributable to unidentified genetic loci, aside from the HD locus.

The spectral radiance dE ? / d? peaks at 160.23 GHz, in the microwave range of frequencies . ( Alternatively, if spectral radiance is defined as dE ? / d?, then the peak wavelength is 1.063 mm . ) The glow is very nearly uniform in all directions, but the tiny residual variations show a very specific pattern, the same as that expected of a fairly uniformly distributed hot gas that has expanded to the current size of the universe.

Where \ textstyle { m ( \ mathbf { s } ) } is the deterministic part of soil variation, \ textstyle { \ varepsilon'( \ mathbf { s } ) } is the stochastic, spatially auto-correlated part of variation, and \ textstyle { \ varepsilon " } is the remaining residual variation ( measurement errors, short-range variability etc . ) that is also possibly dependent on \ textstyle { \ mathbf { s } }, but it is not modeled.
