AMCM99问题-A大碰撞 NASA(航空航天管理局)常常考虑这样一个问题一颗较大的小行星与地球 的碰撞将会产生怎样的后果。 作为这个问题的一部分,要求你们讨论这颗小行星该到地球南极所造成的后 果,有人认为其后果将与该行星撞到地球其它区域的后果有很大的不同。 你们可以假设这颗小行星的直径大约为100米,并且立接撞在南极点处

Direct determination of the joint probability density of several functions o several ra andom variables Suppose we have the joint probability density function of several random variables x, Y, Z, and we wish the joint density of several other random variables defined as functions xyz

This is the main reason why use of the characteristic function is convenient This would also follow from the more devious reasoning of the density function for the sum of n independent random variables being the nth order convolution of the individual density functions-and the knowledge that convolution in the direct variable domain becomes multiplication in the transform domain

Special case: [(P)] is rational: In this solution formula we can carry out the indicated integrations in literal form in the case in which [(P)] is rational. In our work, we deal in practical way only with rational,sn, and, so this function will be rational if D(p)is rational This will be true of every desired operation except predictor. Thus except in the case of prediction, the above

The estimate of x based on N data points can then be made without reprocessing the first N, points. Their effect can be included simply by starting with pseudo observation which is equal to the estimate based on the first N points having a variance equal to the variance of the estimate based on N The same is true of the variance of the estimate based on N
