The memory requirements are linear in the number of simulation points and if more than one simulation under a model is needed, subsequent simulations are much faster than the first. The algorithm can be modified to simulate certain differentiable nonstationary intrinsic random functions, to which ...
Every time function is called for a specific value of D it is generating random numbers .For 1 main program simulation it should have more than 100 iterations of this loop, and also i am unable to generate plot inside the calling function 댓글을 달려면 로그인하...

先来看一个简单情况,不考虑random error term,也就是假设y=f(x)。Gaussian process的定义上就是说从这个随机过程任意取一些随机变量,他们服从多维正太分布,换句话说,f(x) 服从一个多维正太分布,f(x*)服从一个多维正太分布,(f(x)’,f(x*)’)’仍然服从多维正太分布,然后呢,多维正太分布有一个非常好的...
Simulation of Gaussian Random FieldsPaulo Justiniano Ribeiro JrPeter J. Diggle
Functions with mixed discrete/continuous distribution, random sets or coregionalizations between a function and a random set can be modelled using gaussian random functions. In these cases, the conditions at experimental points are expressed in terms of inequalities: 1 ≤i≤n,ai≤Xi≤bi. The sim...
5.7.1 Gaussian Random Fields The simulation of Gaussian random fields is important in the study of spatially distributed data, both as a means of investigating the properties of proposed models of spatial variation and as a way of constructing goodness-of-fit tests by the Monte Carlo method. Wh...

If it is required to evaluate the Q-function at a negative value, the relationship Q(x) = 1 – Q(–x) can be used. That is, to evaluate Q(−2), for example, Q(2) can be evaluated and then use Q(−2) = 1 – Q(2). Example 3.7 A random variable has a PDF given by...
