Found that the most ideal material characteristics for the strongest soft-tissue ingrowth were (1) a pore size ranging from 500 to 600 mm and (2) 30% randomness.

This essay introduced the method and the empirical results of run test, Dickey-Fuller test and variance ratio test on the efficient market hypothesis. Furthermore, reviewed the volatility test method and empirical result on the EMH which relative to the tests based on stock market return.

摘 要：介紹了市場有效性假定的游程檢驗午夜免费一级，DF檢驗以及方差比檢驗的方法和相關(guān)實證研究的結(jié)果人人爱人人人操人人干，與以上基于股票市場收益的市場有效性檢驗相對應(yīng)，對市場有效性假定的波動性檢驗方法以及實證結(jié)果進行了述評色色网址网站。

Using augmented Dickey-Fuller test, the result shows that BDI logarithm series is nonstationary but the first difference is stationary, i. e. it is integrated of order one. High-level ARCH effect was certification in the BDI logarithm series by ARCH LM test, and GARCH (1, 1) model was used to eliminate the conditional heteroscedasticity. Through variance ratio test, the result shows, that the random walk hypothesis of BDI logarithm series can be rejected and international dry bulk shipping market is inefficient.

運用ADF檢驗方法對BDI的對數(shù)序列進行平穩(wěn)性和單整檢驗a毛片黑色丝袜，結(jié)果證明BDI對數(shù)序列是一個非平穩(wěn)過程，經(jīng)一階差分后是平穩(wěn)過程自拍日韩美女视频网站，即BDI對數(shù)序列是一階單整過程久久精品免费一区二区喷潮；通過ARCH LM檢驗認為BDI對數(shù)序列存在高階ARCH效應(yīng)，并用GARCH(1偷国产乱人伦精品一区二区，1)模型消除了殘差序列的條件異方差性摸,吸,操,插,干；通過方差比檢驗法對國際干散貨航運市場的收益率序列進行了檢驗，結(jié)果顯示BDI的對數(shù)序列的隨機游走假設(shè)被拒絕岛国电影人人操，國際干散貨航運市場不是一個有效的市場亚洲欧美va在线播放69。
