Concept explainers
Mersenne primes. As of February 2016, the largest known Mersenne prime was 274, 207, 281−1, which we will call m. If we were to write out m, it would have 22, 338, 618 digits. To put the size of this number in perspective, assume that a typical page in your word processor has 30 lines with 72 characters per line. Do the following calculations:
a. Divide 22, 338, 618 by the number of characters per page to find the number of pages that would be required to print out m.
b. Take the number of pages that you found in part (a) and multiply it by 11 inches to determine the length of the paper (in inches) required to print m. Next, divide this number by 12 to find the length of the paper in feet.
c. Divide the number that you found in part (b) by 5, 280 (the number of feet in 1 mile) to determine the length of the paper in miles.

Standing at point A he measures the angle of elevation from the ground to the top of the building to be 30 degrees. He steps back 100 feet and again measures the angle of elevation and finds it to be 15. (See Figure 12.26.)

Define an ARMA(p,q) process {X} in terms of {+} and state (without proof) conditions for {X} to be (i) weakly stationary and (ii) invertible. Define what is meant by an ARIMA (p, d, q) process. Let {Y} be such an ARIMA(p, d, q) process and show how it can also be represented as an ARMA process, giving the AR and MA orders of this representation.
