projects and research

Time Series Analysis of Geomagnetic Pole Position - Independent Research Project 

  • Conducted time series analysis using R, preprocessed data for quality analysis and applied data transformation techniques to isolate trends, seasonality, and residuals.
  • Performed diagnostic tests, residual analysis, and model performance evaluation.
  • Successfully identified ARMA models for predicting future pole positions, aiding in data-driven decision making.


Advanced Predictive Modeling - Kaggle Prediction Competition 

  • Developed predictive models using regression and machine learning techniques in R.
  • Processed training and test datasets, implemented multiple models including decision trees and lasso regression.
  • Tuned model parameters, evaluated performance using cross-validation and MSE, and submitted results for a Kaggle competition.
  • Enhanced skills in data analysis, model selection, parameter tuning, performance evaluation, and R programming.


Statistical Analysis Project - Impact of Student Habits on Test Scores

  • Studied data from 110 students to see how various factors influence their test scores.
  • Conducted exploratory data analysis and developed a regression model, iteratively refining it to highlight significant predictors.
  • Validated the model using assumptions of linearity, independence, constant variance, and normality of errors.
  • Provided data-driven insights on student habits' influence on academic performance, supporting educational strategies.
