(a) Why does one have to ensure that a function is properly
normalized?
(b) Normalize the function e-r over the interval 0≤ r
≤ inf; 0≤ θ ≤ π; 0≤ ϕ ≤2π
For the following processes, compute autocovariance
function.
(a) AR(2) - use the recursive method;
(b) ARMA(1, 1) - you may use the linear representation from
lectures;
(c) ARMA(1, 2) - derive a linear representation first!
1) Define and elaborate upon the following:
(a) A probability density function
(b) A Poisson distribution
(c) A hypergeometric distribution
(d) What does the value of a probability density function
denote?
Why is the amplitude of the Power spectral density higher for
shorter period of time as compared to a longer period of time when
calculated for any vibration data?

In certain conditions, AR collections and AR management is the
most important function a company has to complete. explain the
first sentence. Provide a brief profile of the type of company that
must put AR management first in importance. How can Treasury help
ensure the viability of a company's future through AR
management?
A random variable has a triangular probability density function
with a = 50, b = 375, and m = 250.
What is the probability that the random variable will assume a
value between 70 and 250? If required, round your answer to four
decimal places.
What is the probability that the random variable will assume a
value greater than 280? If required, round your answer to four
decimal places.
