- And then , adopting the same model , cyclic moment estimation statistic of different orders are constructed respectively , large sample variance expressions of the estimator through theoretic analysis are derived , as well as the constraint relation of estimator performance and noise statistical characteristic . the curve of estimation performance is obtained through monte carlo simulation test , which proves the related conclusion derived
然后，論文同樣以加性和乘性噪聲聯(lián)合干擾下的復(fù)諧波信號和復(fù)線性調(diào)頻信號為觀測模型，分別構(gòu)造了基于不同階次的循環(huán)矩估計量，從理論上推導(dǎo)出了估計量的大樣本方差表達式，分析了估計量性能與噪聲統(tǒng)計特性的約束關(guān)系，通過monte - carlo仿真試驗得到了估計性能的曲線，驗證了推導(dǎo)的有關(guān)結(jié)論。 - In chapter 3 we analyze a useful statistical method - projection pursuit ( pp ) , including its basic theory and application . we put out definitions of projection index and projection pursuit , then prove that pca is a special case of pp with sample variance as projection index and list some indices often used . in section 3 . 3 we apply pp with information divergence index to hyperspectral image , and demonstrate the advanced ability of it by the comparison between it and pca
第三章圍繞一種新興的統(tǒng)計降維方法? ?投影尋蹤展開討論，概述投影尋蹤的一般理論，定義了投影指標(biāo)和投影尋蹤的概念，證明了傳統(tǒng)的主成分分析方法是投影尋蹤的一個特例，證明了正態(tài)性與friedman指標(biāo)為0的等價性；第三節(jié)針對高光譜圖像處理問題，從實例和理論兩個方面，論證了以信息散度為指標(biāo)的投影尋蹤方法在提取信息的能力上優(yōu)于以方差大小作為衡量信息量多少標(biāo)準(zhǔn)的主成分分析方法。
- sample varianceとは意味：標(biāo)本分散
