摘要多元回歸里的標準化回歸系數常被用來表達一個自變項的作用、預測力或解釋力。The use of wave packet to analyze the dynamics of quantum mechanical systems is an increasingly important method to the study of the classical - quantum correspondence. using the quantum gaussian wave packet analysis method, we calculate the autocorrelation function of the rectangular billiard, the peak positions of the autocorrelation function match well with the periods of the classical periodic orbits, which show that the period of the classical orbits can be produced by the time - dependent quantum wave packet method. we also discuss wave packet revivals and fractional revivals in the rectangular billiard, the results show that there are exact revival for all wave packet at each revival time. we find additional cases of exact revivals with short revival times for zero - momentum wave packets initially located at special symmetry point inside the billiard
利用波包分析量子力學體系的動力學行為在研究經典和量子的對應關系方面越來越成為一個非常重要的方法.利用高斯波包分析方法，我們計算了矩形彈子球體系的自關聯函數，自關聯函數的峰和經典周期軌道的周期符合的很好，這表明經典周期軌道的周期可以通過含時的量子波包方法產生.我們還討論了矩形彈子球的波包回歸和波包的部分回歸，計算結果表明在每一個回歸時間，波包出現精確的回歸.對于動量為零的波包，初始位置在彈子球內部的特殊對稱點處，出現一些時間比較短的附加的回歸The object of this thesis for a master ' s degree is to study the existence of seasonality effect in shanghai and shenzhen a - share market. we use the return data of a - share indices ranging from july 21st, 1997 to the end of year 2000 to study this effect by employing five different asymmetric garch - m models. before the garch analysis this paper studied the detail in very detail and find that the data is not much different from the index returns from developed market : it is fat tailed, with high kurtosis
本研究首先對選取的樣本? ?中國的上海和深圳兩個股票市場a -股綜合指數1997年7月21日到2002年12月31日間1316個交易日的收益率的數據分別進行了深入的分析，發現滬深兩市已經逐步趨于規范化，其指數收益率分佈具有明顯的尖峰、厚尾的特點；然後分別運用了ljung - boxq檢驗和增廣的dick - fuller檢驗，發現所研究的兩個市場的收益率都具有明顯的自相關性，並且都是穩定序列；最後利用white異方差檢驗和arch性檢驗，證明了本文所研究的樣本具有明顯的異方差性和顯著的arch效應，因此用自回歸條件異方差模型來研究中國股市的季節效應非常合適。The mathematic model of automatic matching of gas - well production decline for abnormally pressured gas reservoir is developed, based on lm ' s automatic matching of production decline, combined with the regression analysis
摘要在lm產量遞減自動擬合方法的基礎上，結合回歸分析建立了異常高壓氣藏氣井的產量遞減自動擬合數學模型。Based on the general design of bent structure. aiming at multi - complexion bent structure, the essay calculates the dynamic period and domino effect of earthquake, 66 groups in all about shearing force ( q ) and crooked ( m ) of control section. the essay chooses appropriate regress parameter through repeating attempt, and makes use of origin regress analysis program protract dot chart of multi - structure, through multinomial regress analyse, finally works out the simplified formulas for single - stride bent with different stride shearing force ( q ) and crooked road ( m ) of control section
以排架結構常規設計為基礎，針對多種工況下的排架結構，計算了自振周期、地震作用及其效應，共有66組控制截面的剪力q和彎矩m 。然後經過反復嘗試選定合適的回歸參數，利用origin回歸分析程序繪出各類結構的散點圖，經過多項式回歸分析，得到單跨排架不同跨度時控制截面剪力和彎矩的簡化計算公式。分享友人
