Blue
Blue is the
colour between
violet and
green on the
optical spectrum of visible light. Human eyes perceive blue when observing light with a wavelength between 450 and 495 nanometres. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while those with a lower frequency and a longer wavelength gradually appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. In painting and traditional
colour theory, blue is one of the three
primary colours of pigments, along with red and yellow, which can be mixed to form a wide
gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Blue is also a primary colour in the
RGB colour model, used to create all the colours on the screen of a television or computer monitor.
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.
