The primary of Bayesian estimation is to deduce the conditional distribution function of unknown variables on the data, which is also called posterior probability density function ( PPDF). 它是根据测量的数据推导未知变量的条件分布函数,也就是后验概率密度函数,而热传导反问题的数值解就是后验概率密度函数的数学期望。
According to the relation of conditional failure rate function and Multivariate lifetime distribution built, we discuss some important qualities related to conditional failure rate function and apply the depiction to some examples. 由建立的条件失效率与多维寿命分布之间关系,讨论了一些与条件失效率相关的重要性质,并举例说明这种刻画的运用。
The research methods are: using the conditional probability theory to work out the moment generating function of process S ( t) and its distribution function; 研究方法为:利用条件概率证明过程S(t)的矩母函数以及其分布函数;
The spectral parameters were predicted using the conditional probabilistic distribution function based on the pitch and were modified synchronizingly with the pitch using the sinusoidal model. 频谱参数的预测公式由各基频下的条件概率密度函数导出,频谱参数的修改通过正弦模型实现。
In the situation of structural performance function consisting of non normal dependent random variables, conditional probability distribution function of the variables and the inverse functions will be necessary for calculating structural second order reliability index by using Point Fitting SORM [ 1]. 对结构功能函数为相关非正态随机变量构成情况,使用PFSORM算法确定结构二次可靠指标须使用随机变量的条件分布函数及其反函数。
