prior density
解釋
先驗密度-
The class of distributions includes the weibull, burr - type x, pareto and beta distributions. a proper general prior density function is suggested, and predictive density functions are obtained in one - and two - sample cases when the history sample is a type ii double censored sample. illustrative examples are given
在type雙刪失數據場合下，討論了雙參數burr - type分佈參數的貝葉斯估計，在所取的損失函數分別為平方損失， linex損失，熵損失函數下得到了參數的貝葉斯估計，並且給出一種近似演算法。 -
We consider that the complexes of bmon ( m, n > 1 ) or the point defects induced by heavily boron doping may be involved in the nucleation of oxygen precipitates at high temperature range of crystal cooling. therefore it is reasonably deduced that the density of voids in hb cz silicon increases and the size of voids decreases due to the reduction of vacancy concentration as a result of heavy boron - doping enhanced oxygen precipitation prior to the void formation
在實驗事實的基礎上，我們認為在重摻硼硅單晶生長過程中， bmon （ m ， n 1 ）復合體或摻b引起的點缺陷能在晶體冷卻過程中的較高溫度階段形成，且在隨后的退火過程中能穩定存在，作為氧沉澱形核的核心，從而促進了氧沉澱，減小了大直徑硅單晶中void缺陷的尺寸，增加其密度。 -
Finally, a new kind of methods on how to classify a sample into one of the several known populations in terms of posterior probability ratio established by the sample ' s predictive density functions when the unknown parameters " prior distributions are diffuse prior and minnesota prior or normal - inverted wishart distribution
最後，利用參數的充分統計量，根據后驗概率比構造了一類新的基於擴散先驗分佈和正態?逆wishart先驗分佈的多總體貝葉斯分類識別方法。 -
The suburbanization of the united states was prior to the other countries in the world, vvhich had its own characteristics : it mainly was a process of natura ! spread from the city ? re to the outer ; during the process, it was very obvious that the social stratum differed according to region ; besides, it also presented the characteristics of extension with low density and decentralization
美國的郊區化走在世界各國之先，有其特徵：它主要是一個從城市核心向外自然擴展的過程；郊區化過程中，社會階層地域分異比較明顯；還呈現出低密度蔓延和分散化的特徵。 -
Kde is a non - parametric method which is capable of extracting the population ' s probability density function ( pdf ) based on data sample only without any a prior knowledge about the statistic properties of the data regime. in this thesis, it is conducted the implementation of the kde for monitoring the performance of batch production processes
用核函數法概率密度估計對間歇生產過程進行實時狀態監測的主要優點是它屬于非參數法概率密度估計的一種，不需要數據總體的任何先驗知識或是假設而直接基於實測數據樣本求出總體的概率分佈密度函數，擺脫了對不可靠的先驗知識的依賴。 -
There exists a strong correlation between initial surface morphology prior to ht growth and ht gan growth mechanism and eventual threading dislocation density in epilayers
發現高溫生長前樣品的表面狀態對隨後生長的gan生長機制及最終外延層中的位錯密度有很大影響。 -
In ps alt, we obtain the bayesian estimation of each parameter and marginal posterior density when the prior density of shape parameter is continuous using laplace method under ce model. in ssalt, we obtain the bayesian estimation of each parameter using the same method
在序加試驗下，對于逆冪律模型，給出了參數的bayes統計分析，並利用laplace方法解決了分佈的形狀參數取為連續先驗時各參數的bayes估計和參數后驗邊際密度。 -
Prior to 1948 the develop arena in the u. s. largely resembled that of europe by being focused mostly on cities and high density mixed - use and commercial projects
1948年前，美國的發達地區比較接近歐洲，重點放在城市的反展和高密度，多用途和商業項目上。
