    當估計量無偏時，數字估計值也常叫做無偏的。
  2. We make the following assumption for when 2 is positive definite matrix, different estimators about matrix of regression coefficients and inefficiency of least squares estimate have been discussed in many documents. considered 2 is nonnegative definite matrix, this thesis derives best linear unbiased estimate of parameter matrix b and estimable parameter function kbl under the meaning of matrix nonnegative definite and the property of maximum probability of blue is investigated. next, we discuss some necessary and sufficient conditions of the equality of the lse and blue, then we derive the estimation of the deviation bet - ween the least squares and the best linear unbias estimators of the mean matrix, meanwhile a relative efficiency of lse ofb is proposed and its bound is given

    當0時，眾多文獻討論了回歸系數陣的各種估計及lse的有效性，本文考慮了當0的情形，給出了回歸系數陣b及其可估參數函數kbl的在矩陣非負定意義下的最優估計（ blue ） ，研究了它的一個最大概率性質，並且討論了最小二乘估計成為最佳線性無偏估計的充分必要條件，在此基礎上給出了均值矩陣的最小二乘估計與blue的偏差估計，定義了lse相對于blue的一個相對效率，並給出了它的界。
  3. In this study, a paired - comparison method for which we designed an internet questionnaire was applied to evaluate the relative monetary values for forest public goods and services which have no defined market value or no known monetary value

  4. In the third section three different forms of heteroscedasticity are used in the random simulation and then park test, glejser test and goldfeld - quandt test are compared although the existence of heteroscedasticity does not destroy the unbiasedness of the ols estimators, the variances become larger

    異方差的存在雖然並不破壞普通最小二乘估計量的無偏性，但是估計量的方差變大了。由於估計量方差的變大，就使通常假設檢驗的值不可靠。
  5.

    在emh理論形成的過程中，奧斯本osberne和法瑪fama的貢獻最大。奧斯本提出了關于股票價格遵循隨機遊走的主張，認為投資者是根據他們的期望價值或收益率來估計股票的，而期望價值是可能的收益率的概率加權平均值，所以投資者在奧斯本定義上的理性是以無偏的方式設定其主觀概率。
  6. Some issues associated with the algorithm such as wavelet function selection, analysis level, and boundary treatment and so forth have been discussed. the stein self - adapting threshold denoising method is used to the signal pretreatment, thus the snr and resolution are improved
