Can someone help me with part (c), (with detailed explanation)
First WKT if Xi's are IID then SUM(Xi) follow binomial distribution with parameters n and p. now we obtaon limiting case as-therefore the distribution of sum(Xi) vconverges to a poisson distribution with parameter lemda. here we can say that for p is less then 0.10, with large n we obtain poisson distribution. and another thing is that sum(Xi) follow poisson distribution for large n and small p but mean of x follow S.N distribution for large n.

I don't understand a iii and b ii, What's the procedure of deriving the limit distribution? Thanks. 6. Extreme values are of central importance in risk management and the following two questions provide the fundamental tool used in the extreme value theory. (a) Let Xi,... , Xn be independent identically distributed (i. i. d.) exp (1) random variables and define max(Xi,..., Xn) (i) Find the cumulative distribution of Zn (ii) Calculate the cumulative distribution of Vn -Zn - Inn (iii)...

Assume that we have three independent observations: where Xi ~ Binomial(n 7,p) for i E { 1.2.3). The value of p E (0, 1) is not known. When we have observations like this from different, independent ran- dom variables, we can find joint probabilities by multiplying together th ndividual probabilities. For example This should remind you the discussion on statistical independence of random variables that can be found in the course book (see page 22) Answer the following questions a...
(3) Suppose that the intensity of the Poisson process describing the crystallization nuclei is time dependent and given by 1 + g(t), where g(0) = 0 and g is continuous and monotonically increasing (take g(t) = et as an example).

part b and c In class we derived a Fokker-Planck equation for the velocity distribution P(et) starting from the assumption of small random changes in velocity at each time step f.(t) where f(t) is chosen from a distribution WU: ). Einstein's original approach to Brownian motion had a different starting point, focusing on position differences at each time step x(t + Δt)-x(t) + E(t) where £(t) is a random displacement chosen from some distribution W(E). Underlying this ap- proach is...
