The Blue

The Blue is a central market place in Bermondsey an area in London. The market is open Monday to Saturday from 9am until 5pm and has about 10 stall holders, selling food and clothes. The area has been known as The Blue for more than two hundred and thirty years and is probably named after the original Blue Anchor public house that gave its name to Blue Anchor Lane. The market has capacity for 24 stalls.

Immediately north of Blue Anchor Lane on an arched viaduct are the multiple railway tracks of the Brighton and South East Main Lines. The Blue Anchor Lane joins St. James's Road where the viaduct arches to the immediate north west contain the remnants of the disused Spa Road railway station which was the original terminus of London's first railway.

In 2005 a Metropolitan Police report described the area as a crime hotspot for "race crime and youth disorder". In 2009 during the funeral procession of Jade Goody a white dove was released at The Blue, where her family once had a stall.

The Blue Hearts

The Blue Hearts (ザ・ブルーハーツ, Za Burū Hātsu) were a Japanese punk rock band active from 1985 to 1995. They have been compared to such bands as the Sex Pistols, The Clash and the Ramones. In 2003, HMV Japan ranked them at number 19 on their list of 100 most important Japanese pop acts. In September 2007, Rolling Stone Japan rated their self-titled debut album number 3 on its list of the "100 Greatest Japanese Rock Albums of All Time".

Career

Its members were Hiroto Kōmoto (vocalist), Masatoshi Mashima (guitarist), Junnosuke Kawaguchi (bassist) and Tetsuya Kajiwara (drummer). Mikio Shirai was not an official member of the band, but often toured with them as their keyboardist. Formed in 1985, the group made its major debut in May 1987, and released its first album, the self-titled The Blue Hearts, and followed that up with seven more albums. Though they started on an independent label, each album sold more copies than the previous one, with their last recording selling in the millions. In 1990, The Blue Hearts had a self-titled EP released in the United States, which they supported with a US tour.

Gauss–Markov theorem

In statistics, the Gauss–Markov theorem, named after Carl Friedrich Gauss and Andrey Markov, states that in a linear regression model in which the errors have expectation zero and are uncorrelated and have equal variances, the best linear unbiased estimator (BLUE) of the coefficients is given by the ordinary least squares (OLS) estimator. Here "best" means giving the lowest variance of the estimate, as compared to other unbiased, linear estimators. The errors do not need to be normal, nor do they need to be independent and identically distributed (only uncorrelated with mean zero and homoscedastic with finite variance). The requirement that the estimator be unbiased cannot be dropped, since biased estimators exist with lower variance. See, for example, the James–Stein estimator (which also drops linearity) or ridge regression.

Statement

Suppose we have in matrix notation,

expanding to,

where are non-random but unobservable parameters, are non-random and observable (called the "explanatory variables"), are random, and so are random. The random variables are called the "disturbance", "noise" or simply "error" (will be contrasted with "residual" later in the article; see errors and residuals in statistics). Note that to include a constant in the model above, one can choose to introduce the constant as a variable with a newly introduced last column of X being unity i.e., for all .
