Cointegration Analysis of Respiratory Health & Pollution
Some initial analysis and brief methodology behind my ARDL modeling approach to relating chronic respiratory and ambient pollution.
Temperature Analysis
Udacity's Data Analyst Nanodegree Project 1
Exploratory Analysis: Residential Burglary Rates by CA County
This report provides some exploratory analysis for my STAT 530, Experimental Design and Analysis research project. My research partner and I utilized these plots in our final report. I provide the code and output to showcase the use of ggplot2 and maps.
Linear Regression Homework 2
Homework from my linear regression course at CSU Long Beach showcasing interval estimation and linear models.
Linear Regression Homework 3
Homework from my linear regression course at CSU Long Beach showcasing regression methods using linear algebra.
Linear Regression Homework 4
Homework assignment showcasing R code used for model selection using forward, backward and all-possible regressions (AIC, Mallow's CP).
Linear Regression Midterm
R code and output from my Linear Regression course at CSU Long Beach. The questions showcase code for identifying outliers, leverage and influential points and model selection.
Predictions on NBA Salaries Using Linear Models
Project for Linear Regression (Stat 510) CSU, Long Beach. Luis Cervantes and I used linear regression methods to find a suitable model for prediction of NBA player salaries using some common player statistics scraped from the web. This was a graded assignment.
Open Source Survey Data Analysis
I look over the Open Source Survey 2017 data set and look for a few key variables such as gender, education, employment and what type of code contributions those who are on Github make. This analysis accompanies a survey design analysis for my Survey Design (Stat 483) class at CSULB in the Applied Statistics Master's Program.
Analysis of Activity Data
Coursera Peer Assessment 1, analyzing the activity data set to compare the activity throughout the day of people wearing a FitBit type band. I compare the activity on weekdays and weekends to see if there is a significant change in activity levels.
Motortrend Data Analysis
Coursera Data Science project looking over the Motortrend data set provided to us by Coursera. I decided to analyze the miles per gallon efficiency of cars based on transmission type, and also create a model to find the most important factors on mpg overall.
Tooth Growth Analysis
Coursera Data Science project presenting an analysis of the Tooth Growth data set provided in R.
Exponential Exploration
Coursera Data Science project on exponential distributions and the central limit theorem. Provides visualizations and simple simulations to show key concepts behind the versatility of the exponential family.
Reproducible Research Peer Assessment 2
Introductory Analysis of The U.S. National Oceanic and Atmospheric Administration’s (NOAA) storm database
