  1. Multiple regression models can accommodate many explanatory variables that may be correlated

    多元回歸模型能容許很多解釋變量，而這些變量可以是相關的。
  2. Why ? it is highly possible that because explanatory variables are highly correlated, the resulted large standard errors could indicate an parameter to be insignificant while it is indeed significant

    為什麼？解釋變量很可能高度相關，即使變量實際上顯著，結果中的較大的標準差也可能表明參數不顯著。
  3. A new type of viscoelastic stochastic finite element method is established using first - order perturbation theory based on local averaging method of random field and karhunen - loeve expansion theory of random process. the amount of computations is greatly reduced by transforming correlated random variables to a set of uncorrelated random variables. the relations of different random response variables are analyzed and monte carlo simulations for viscoelastic stochastic structures are investigated

    通過實證檢驗，一方面證實了股市行情對宏觀經濟和貨幣供應量等指標具有明確的反映;另一方面從因果關系方面說明宏觀經濟和貨幣政策是股市行情變化的原因，而股市對宏觀經濟有影響，但作用尚不明顯。

  6. The empirical research in em forthers the acaden1ic thoughts of accrual - basis accounting, hastens the development of generally accepted accounting principles, and enriches the research measures in empirical accounting lots of literatures on em have been reported rece11tly however, researcheres have n ' t reached the consensus in most issues in this fieid much of the controversy over the interpretation of the literature ' s tindings is due to the extensive use of aggregate accruals models that mostly origil1ated from jones mode1 given the limlted theory, we have of how accruals behave in the absence of discretion, the task of identifying and controlling for potentially correlated o111itted variables is daunting indeed an alternative to study aggregate accruals is the 111ethodology for identifying earnings management developed by burgstahler and dichev ( l997 ) based on the distribution of earnings after management however, this measure is flawed by its silence about the form and extent of earnings management my dissertation intends to bridge the traditional aggregate accruals models and the new earnings distribution method, which is the first aim of this paper there is no doubt that earnings management is more rampant in china when compared with what has been documented for the west, since china ' s accounting standards are much too incomplete to of lbr clear guida11ce on many accounting transactions

    文章首先指出了研究盈餘管理的三種方法各自的優點及不足，然後創造性地發展了前人的研究手段，在傳統的瓊斯模型及新的盈餘分佈方法之間找到了溝通的橋梁，並建立了一個嶄新的模型：瓊斯?閾值模型。通過對美國18 ， 160家上市公司在1980 - 1999的20年間的40餘萬觀測樣本的實證研究表明，美國上市公司與我國上市公司一樣也存在著以獲取正盈餘及維持近期業績為目的的盈餘管理；公司經理人員使用可操縱性應計利潤為其管理盈餘的手段；經理人員因追求正盈餘或試圖維持近期業績而管理盈餘時體現出不同的行為方式。對美國上市公司的成功運用，證明我們的新模型在判斷盈餘管理存在與否、手段如何、動機怎樣等方面均比目前正在學術界流行的盈餘分佈法具有更強的檢測能力。
  7. I find that the chinese stock market size was significantly and positively correlated with economic growth and saving deposits rate, even after controlling for other growth inducing variables. on the basis of this, the dynamic interaction relationship between stock market development and economic growth of china is examined in a bivariate vector autoregression ( var ) framework. i find there is one positive cointegration between stock market capitalization and economic growth, uni - directional causality from gdp to the stock market capitalization, but the stock market shock can influence the output positively

    我們在兩變量向量自回歸模型框架下考察了中國經濟增長與股票市場發展之間的動態互動關系：股市規模與總產出之間存在著正向的協整關系，表明兩者在長期上是均衡發展的；格蘭傑因果檢驗顯示兩者間存在著經濟增長股票市場規模發展的單向因果關系，沖擊響應分析結論指出股票市場和經濟增長之間有著一種互動關系，股票市場和經濟增長的正向變動均會給對方帶來永久的正向影響，但目前股票市場沖擊對產出的這種影響還很微弱。
  8. Ambagaspitiya ( 1998 ) considered a general method of constructing a vector p ( p 2 ) dependent claim numbers from a vector of independent random variables, and derived formulas to compute the correlated aggregate claim distribution for corresponding common shock model with p dependent classes of business. cossotte and marceau ( 2000 ) used a discrete - time approach to study how the common shodcaffects the finite - time ruin probabilities and the adjustment coefficient

    Ambagaspitiya （ 1998 ）通過向量的方法解決了一類索賠次數相關的風險模型，推導出了最大損失量的表達式； cossetteandmarceau （ 2000 ）考慮了離散時間下相關是如何影響有限時間的破產概率與調整系數的問題； yuen ， k
  9. When > 0, and the independent variables are positively correlated over time, the second term is positive, so the usual ols variance underestimates the true variance of the estimator

    當> 0 ，而且自變量在時間上是正相關時，第二項為正，因此通常的ols方差低估了估計量真實的方差。
  10. To further understand the space - time structure of hydrological variables, the observed values at each measurement site are considered as separate but correlated in the one - dimensional time series

    為了更進一步?解水文變數之時空架構，每個測站觀測資料視為一維時間序列，但測站與測站間關系為二維空間結構。
