• Titanic Passenger Survival Prediction Using Classification Models
  Developed a logistic regression model to predict passenger survival on the Titanic using cleaned historical data. Identified key predictors—passenger class, sex, age, and number of siblings/spouses aboard—via stepwise feature selection. Achieved 80.9% accuracy, with clear interpretability highlighting lower survival rates for males, older individuals, and lower-class passengers. Simulated survival probabilities for common passenger profiles to support model validation and insight communication. View full PDF report with plots and tables
