Cholesky factorization versus QR factorization. In this problem we compare the accuracy of the two methods for solving a least-squares problem minimize Ar - b We take b10- 1-10-k ke A10 0 10k for k 6, k- 7 and k 8. (a) Write the normal equations, and solve them analytically (i.e., on paper, without using MATLAB). (b) Solve the least-squares problem in MATLAB, for k = 6. K-7 and k = 8, using the recommended...
please answer all parts
4. Least Square Method A. (10 points) Use the least squares method and find a linear fit for the following points: (0, -3), (2, -3), (1, -4), (4,5) B. Short Answer: (5 points) Quickly plot the points (by hand) and comment on the likely quality of the linear fit. Would another type of curve fit be better suited?
please write down detailed solution (do not copy
3. [Polynomial interpolation versus least squares fitting, 10pts] Recall how Q7 in HW3 required you to find the cubic best fit to six given data points. This led to a least squares optimization problem. We are given the same points as in HW3: i 01 | 2 | 3 | 4 | 5 X 0.0 0.5 1.0 1.5 2.0 2.5 Y 0.0 0.20 0.27 0.30 0.32 0.33 (a) Write down the least...
Please use R, Python or by hand A student looks their horoscope rating every morning before taking an exam. The student keeps a log of the horoscope ratings and the exam performance. This is the log: H = [3, 4, 9, 10, 6, 7] E = [80, 90, 75, 95, 85, 85] Test if least squares regression produces a significant F statistic: F = MSRegression MSResidual = (SSY −SSE)/k SSE/(n−k−1) a) What conclusion can you arrive at?
3. (40 points) Use the graph, an output of the least squares prediction equation for the starting salary data (in thousands of dollars) given a graduated student's cumulative GPA, and the table of sampled data below to do the following Student ID GPA(x) 3.26 Starting Salary (y) 33.8 2.60 29.8 3.35 33.5 2.86 30.4 3.82 36.4 2.21 27.6 3.47 35.3 Regression Plot Y= 14.8156 + 5.70657x R-Sq 0.977 寸 853 4.0 2.0 2.5 3.0 3.5 GPA (a) Identify and interpret...

Problem 1 Please do not use any type of software to solve this problem; perform all the calculations and draw the charts by hand. You can use your calculator only for simple operations like addition, multiplication, finding averages and standard deviations. The owner of an apartment complex with three-bedroom units is trying to determine what rent he should set for the summer months. He believes that the rent of an apartment in his complex determines if it will be occupied...
For this project, each part will be in its oun matlab script. You will be uploading a total 3 m files. Be sure to make your variable names descriptive, and add comments regularly to describe what your code is doing and hou your code aligns with the assignment 1 Iterative Methods: Conjugate Gradient In most software applications, row reduction is rarely used to solve a linear system Ar-b instead, an iterative algorithm like the one presented below is used. 1.1...
please use python and provide run result, thank you!

For this assignment you will have to investigate the use of the Python random library's random generator function, random.randrange(stop), randrange produces a random integer in the range of 0 to stop-1. You will need to import random at the top of your program. You can find this in the text or using the online resources given in the lectures A Slot Machine Simulation Understand...
