A service of the. Howdy juliamb — Thanks for reaching fo. Here is what I am doing. We are just a few steps from knowing how close is our product of Gaussian pdfs to yield another Gaussian pdf! The first statistician takes aim and overshoots.

Gaussian probability density functions pdfwhich have two parameters and this nice syntax -in the unidimensional case When we do not know why and how some measurement varies over time in spite of the underlying system staying invariant apparentlyand in addition have no idea about the internals of the process that is producing that measurement, and in addition we do know that measurements move around a central value with high simmetry, it is usual to bring the familiar and beautiful graph of a Gaussian to light:.

The main reason for the prevalence of this pdf is the formidable evidence that supports find the product of two random variables Central Limit Theoremby which, for example, the sum of many measurements taken from a given random process -independently- divided by the number of them, is thee new measurement which tends to have a Gaussian shape, more and more Gaussian flnd that number of measurements increases. Actually, the CLT works very well in so many disciplines and problems, even when the measurements do not come from identically distributed processes, that Gaussians are taken as the default probabilistic model of uncertainty in countless situations.

Well, sometimes you find in your calculations products of Gaussian functions. Anyway, the difference between a Gaussian function and a Gaussian pdf is that the former does not need to integrate to 1 in its whole hwo. You can find easily in Internet that the product of two Gaussian functions is a Gaussian function. Moreover, in some places you can find even the value for the parameters of the resulting Gaussian pdf of the product of variabled Gaussian pdfsbut again an algebraical deduction is missing, and, more importantly….

It is for certain a Gaussian functionor, in other words, a scaled Gaussian pdf which cannot be called a pdf at all! However, in the case developed in this post, that independence is not assumed. The find the product of two random variables of finnd post is to develop algebraically the product of two Gaussian pdfs defined on the same support, and show the result. Let p1 and p2 be two Gaussian pdfs with the same support :. Ok, it is time to focus only on the exponent of e.

Firstly, we incorporate the previous scale factor into it:. Then we expand the square terms that include x find the product of two random variables. And then we collect the numerator as a polynomial in x :. Casually, we had in the above expresion that polynomial if we do:. We are just a few steps from knowing how close is our product of Gaussian pdfs to yield another Gaussian pdf!

But first, let us take a short detour to obtain the value of C in our expression:. We have already values for A and C. Using those letters, the resulting product of the two Gaussian pdfs has become:. Notice that the first factor and the first exponential are a Gaussian pdf. The whole result, however, is just a Gaussian function, unless the second exponential equals 1…. Let us take a closer look to that second exponential, the reason why our result is not a Gaussian pdf fibd a Gaussian function:.

But what we are interested in is knowing under which conditions this expression equals 1, and, thus, the product of our original pdfs p1 and p2 is actually a Gaussian pdf:. Thus, we will find infinite cases where the product of two Gaussian pdfs is a Gaussian function but not a Gaussian pdf. Animal farm character descriptions quizlet the scaled Gaussian function obtained as the result of the product has the following pdf-like parameters:.

Analogously, there are new homomorphisms considering independent random variables which are concentrated at the right of one point, now with the "maximum" operation and capitalization financial laws, whose instantaneous rates coincide with the growth rates of the correspondent random variables.

This paper relates distribution functions of random variables which are concentrated at the left of one point and discount financial laws, in the way that the error rate of a random variable coincides with the instantaneous rate of the financial law, proving, in case that random variables are independent beween them, that there are correspondences with an homomorphic behaviour between ramdom variables which are concentrated at the left of one point, discount financial laws and rates with "minimum", "product" ande "addition" operations, respectively.
