Regression Analysis

This project was done for an Advanced Methods of Regression class at Virginia Tech. In this project, I used regression analysis to predict student outcomes on a state exam based on different predictor variables.

Housing Market Analysis Dashboard

For a Data Analytics class at Virginia Tech, I was partnered up to create this dashboard showcasing different modeling methods we learned. The methods used in this project include multiple linear regression, logistic regression, kNN classification, LOESS modeling, cublic spline modeling, as well as naive bayes classification.

Statistical Analysis Report

This statistical analysis report on P53 was written for a Communication in Statistics class at Virginia Tech. This is a class a part of the Data Analytics and Applied Statistics Master's program and showcases my ability to take statistical jargon and relay it to different audiences.

Data Exploration in SQL

This project I did a data exploration of a Covid-19 dataset in SQL server. I used joins, CTE’s, windows functions, aggregate functions, as well as created views, and converted data types to help me analyze the data. Afterwards I created a dashboard in Tableau, which you can view by clicking on my “Tableau Projects” link.
