Century Dictionary and Cyclopedia
    • n leek One of several species of the genus Allium; especially, a biennial culinary plant, Allium Porrum. It is distinguished from the onion (A. Cepa) by having a cylindrical base instead of a spherical or flattened bulb, by its flat leaves, and by its milder flavor. It is stimulant and diuretic. The cultivated leek is believed to have originated from the wild leek, A. Ampeloprasum, found in southern Europe and western Asia. It was probably cultivated in ancient Egypt, and may have been the plant called by that name in Numbers xi. 5. According to Pliny, it was made prominent among the Romans by Nero; and at the present day it is still in extensive use. The leek has long been the national badge of the Welsh, traditionally said to have been adopted by direction of St. David, in celebration of a victory of King Arthur over the Saxons. The crow-leek is the bluebell squill, Scilla nutans; the sand-leek, Allium Scorodoprasum, found in sandy places in the middle latitudes of Europe; the stone-leek, A. fistulosum, known as Welsh onion; the vine-leek, A. Ampeloprasum; the wild leek, A. Ampeloprasum, A. ursinum, and, in America, A. tricoccum. (See also house-leek.)
    • n leek Polytelis barrabandi, a small parrot, green with a scarlet breast. Also called green-leek.

And savory, pot-herbs in a row;
With parsly, not unknown to fame,
Gay garland at the Olympic game.

In science:

Several approaches have been proposed, such as dependence kernels (Leek & Storey, 2008), factor models (Friguet et al., 2009) and principal factor approximation (Fan et al., 2012).
Graphical-model Based Multiple Testing under Dependence, with Applications to Genome-wide Association Studies
For example, gene expression measurements may be affected by environmental conditions and experimental procedures (Leek and Storey, 2007; Gibson, 2008), which, unaccounted, would cause reduced power and increased false positive rate in association studies.
Genome-wide association studies with high-dimensional phenotypes
SVA (Leek and Storey, 2007) addresses the problem by first estimating the effect of the factor of interest on each gene then doing factor analysis on the residuals, which intuitively can give good results as long as the UV factors are not too correlated with the factor of interest.
Correcting gene expression data when neither the unwanted variation nor the factor of interest are observed
They apply the method to several datasets in an extensive study and show its very good behavior for differential analysis, in particular comparable performances to state of the art methods such as ComBat (Johnson et al., 2007) or SVA (Leek and Storey, 2007).
Correcting gene expression data when neither the unwanted variation nor the factor of interest are observed
Both α and β are modeled as fixed, i.e., non-random (Robinson, 1991). A similar model was also used in Leek and Storey (2007) and Listgarten et al. (2010).
