12.3 Least angle property of least squares. Suppose the m × n matrix A has linearly independent columns, and b is an m-vector. Let x ATb denote the least squares approximate solution (a) Show that for any n-vector a, (Ax)Tb - (Aa)"(Aâ), i.e., the inner product of Ax and b is the same as the inner product of Ax and Ai. Hint. Use (Ax)b (ATb) and (ATA)2 = ATb (b) Show that when A and b are both nonzero, we...
3. Using Excel to solve the problems below If there is cube which has length I 9m and width w-5m the height of the cube could be represented as h, the total surface area could be calculated as: S-2 (w l +w h+h l) If h increases from 1m to 15m, each time h increases 1m, build a table in Excel to include 2 columns, one is for h and the other is the calculated total surface area S. Plot...
QUESTION 2. Billy’s Fizzy Flavours Inc. wants to estimate the average volume per can of Crazy 88 Cola
with 90% confidence.
(a) In practice, the soft drink producer does not know the population mean or population standard deviation
of the volume per can. However, for the purpose of this question we will assume the volume per can is
normally distributed with a mean of 353 mL and a standard deviation of 2 mL. Use this information and the
Excel procedure...
Terry’s utility of wealth is given by: u(w) = ln(w). Suppose Terry has $1 million in his bank account and a beach house worth $2 million. With probability 1/3, his beach house will get destroyed by a hurricane. (a) Is Terry risk-averse, risk-neutral, or risk-loving? Verify your answer using calculus. (b) Determine the actuarially fair premium for an insurance plan that will compensate him $2 million if his beach house gets destroyed by a hurricane. (c) Write out the two...

Matrix operations 22. Suppose you are given a matrix of the form cos(() - sin(0) R(0) = sin() cos(0) Consider now the unit vector v = [1,0)" in a two dimensional plane. Compute R(O)v. Repeat your computations this time using w = [0, 1]". What do you observe? Try thinking in terms of pictures, look at the pair of vectors before and after the action of R(O). 23. You may have recognised the two vectors in the previous question to...
