This R script performs a logistic regression and discriminant analysis on the Weekly dataset

from the ISLR package to predict stock market movements. In Question 1, logistic regression is

applied to assess the relationship between stock market direction and lagged returns,

evaluating model accuracy on training and testing data. Additionally, Linear Discriminant

Analysis (LDA) and Quadratic Discriminant Analysis (QDA) are used to compare classification

performance. Question 2 applies LDA to a small custom dataset to classify binary outcomes

based on a predictor variable. The model is used to predict class probabilities for new data

points.
