Workshop 2 Solution - Econometric Models Alberto Dorantes, Ph.D. Tec de Monterrey

This document presents an applied statistical modeling lab using data from the 2023 Behavioral Risk Factor Surveillance System (BRFSS), a nationally representative U.S. health survey. The analysis demonstrates key regression modeling concepts in epidemiology including simple and multiple logistic regression, dummy variable coding, interaction testing, model diagnostics, and model comparison, all applied to predicting hypertension among U.S. adults. Key topics covered include building and interpreting logistic regression models, controlling for confounding, testing for effect modification using likelihood ratio tests, checking model assumptions with variance inflation factors and Cook's Distance, and selecting the best fitting model using AIC and BIC. Results show that age and obesity are the strongest independent predictors of hypertension in this sample, with no significant Age × BMI interaction detected. This lab was completed as part of EPID 553 Statistical Inference and is intended as a practical introduction to regression modeling for public health and epidemiology students.

Publikasi ini menyajikan visualisasi bivariat dari dataset diamonds menggunakan R dan ggplot2. Analisis berfokus pada hubungan antara atribut fisik dan kualitas berlian seperti depth, table, cut, color, clarity, carat, dan price melalui density plot, barplot, boxplot, dan jitter plot untuk mengungkap pola proporsi standar, perbedaan rata rata harga, distribusi harga, serta variasi individu berdasarkan karakteristiknya. Diharapkan publikasi ini dapat memberikan wawasan bagi pelaku industri perhiasan, analis pasar, dan akademisi yang tertarik pada analisis harga dan segmentasi produk berlian sehingga keputusan penetapan harga, pengelolaan stok, dan strategi pemasaran dapat dilakukan secara lebih efektif dan berbasis data.

In this R demonstration output, you can see data analysis based on the OLS, PCR, PLS, Ridge and ENET methods.
