Linear Regression and Calculus in R
Problem 1-Transportation Safety: Scenario: You are a data analyst at a transportation safety organization. Your task is to analyze the relationship between the speed of cars and their stopping distance using the built-in R dataset cars. This analysis will help in understanding how speed affects the stopping distance, which is crucial for improving ...

Probabilities and Distributions
Problem 1: Bayesian: Problem Statement: A new credit scoring system has been developed to predict the likelihood of loan defaults. The system has a 90% sensitivity, meaning that it correctly identifies 90% of those who will default on their loans. It also has a 95% specificity, meaning that it correctly identifies 95% of those who will not def...

Geometric Transformation of Shapes and Image Processing
1. Geometric Transformation of Shapes Using Matrix Multiplication Context: In computer graphics and data visualization, geometric transformations are fundamental. These transformations, such as translation, scaling, rotation, and reflection, can be applied to shapes to manipulate their appearance. Task: Create a simple shape (like a square or trian...

Nonlinear Regression Techniques
Nonlinear Regression Techniques Umer Farooq 2024-04-05 Regression Problems on Non Linear Regression Method: Question 1: Friedman (1991) introduced several benchmark data sets create by simulation. One of these simulations used the following nonlinear equation to create data: y = 10sin(\(πx_1x_2\)) + 20(\(x_3\) − 0.5\()^2\) + 10\(x_4\) + 5\(x_5\...

ARIMA Modeling
1) Figure 9.32 shows the ACFs for 36 random numbers, 360 random numbers and 1,000 random numbers. a) Explain the differences among these figures. Do they all indicate that the data are white noise? Answer: Each of the three figures suggests that the data exhibit characteristics of white noise. This is evident as the bars representing the autocorre...
