Web23 nov. 2015 · 5. The Gauss-Markov theorem states that, under the usual assumptions, the OLS estimator β O L S is BLUE (Best Linear Unbiased Estimator). To prove this, take an arbitrary linear, unbiased estimator β ¯ of β. Since it is linear, we can write β ¯ = C y in the model y = β X + ε. Furthermore, it is necessarily unbiased, E [ β ¯] = C E [ y ... In measure theory, an area of mathematics, Egorov's theorem establishes a condition for the uniform convergence of a pointwise convergent sequence of measurable functions. It is also named Severini–Egoroff theorem or Severini–Egorov theorem, after Carlo Severini, an Italian mathematician, and Dmitri Egorov, a Russian physicist and geometer, who published independent proofs respectively in 1910 and 1911. In finance, the Markowitz model ─ put forward by Harry Markowitz in 1952 ─ is a portfolio optimization model; it assists in the selection of the most efficient portfolio by analyzing various possible portfolios of the given securities. Here, by choosing securities that do not 'move' exactly together, the HM model shows investors how to reduce their risk. The HM model is also called mean-variance model due to the fact that it is based on expected returns (mean) and the standar… english teaching job in south korea
