  6. In the recent 50 years, many models such as multivariate discriminate analysis and neural network come out. however, in our country, financial distress prediction just begins. the main reasons are as follows : one reason is the lack of uniform accountant rule before july 1, 1993, the other reason is the difficult of having the financial dates of unlisted companies

    但是，在國內對企業財務困境預測的研究才剛剛起步，並且主要集中在對上市公司財務困境預測的研究上，其主要原因有兩點:一是1993年7月1日之前我國並沒有實施統一的會計準則，缺乏可靠規范的研究數據;二是非上市公司財務數據的獲取十分困難。
  7. The assessed results show that the prediction effect of artificial neutral networks model is better than that of multivariate nonlinear regression model, as well as the forecast effect of subsection model for water content of crude oil is better than that of united model

    評價結果表明：神經網路模型預測效果優于多元非線性回歸模型，原油含水率分段預測模型效果優于統一模型。
  8. One is to derive the optimal prediction and the other is to find its necessary and sufficient conditions. there is, however, a more design matrix in this model than is in multivariate linear model, which has caused difficulties such as solving a exceptional unlinear matrix equation groups especially when deriving the optimal prediction

    但是因為一般增長曲線模型比多元線性模型多一個設計陣，這就給研究帶來了很大的困難，特別是在求解模型的最優預測時，遇到了一類特殊的非線性矩陣方程組，所以在一般情況下我們既無法求出模型的最優預測，也無法找到存在最優預測的充要條件
  9. ( 4 ) it does not like the traditional method to suppose a special designated model concerns between well logging and seismic data. it gains a statistics relation from a series of data training and analysis, which _ is linear relation gained from multivariate regression or nonlinear relation gained from neural net training. ( 5 ) its most important characteristic is using the thought " alternation check " to evaluate the reliability of prediction, and can be used in the optimization of seismic attribute series

    這就允許我們用到迭前和迭后地震數據經過非線性變換的信息: （ 4 ）它不像傳統做法那樣在測井和地震之間假設一種特定的模擬關系，而是在對井點處一系列數據訓練和分析中獲得的一個統計關系，這個關系是通過多元回歸獲得的線性關系，或是通過神經網路訓練獲得的非線性關系: （ 5 ）它最重要的特點是利用「交互校驗」的概念來評估預測的可靠型，並能夠用於地震屬性系列的優化。
