This post gives a simple introduction to popular modern data science technologies. In this post, we will explore features of the Databricks platform and distributed computing with Spark using data that is freely available in the Databricks Free Edition.
torch: Revisiting the Abalone Data Published:
This post demonstrates building and fitting a neural network using the torch package in R. In this post, I revisit the abalone Kaggle competition, which is a supervised regression problem described and analyzed in a previous blog post using tidymodels.

This post provides a walkthrough demonstrating how to use the sklearn package in Python to tune and evaluate multiple supervised classification methods, such as logistic regression and extreme gradient boosting (XGBoost) to predict whether bank customers will close their account. The dataset comes from a past Kaggle competition and contains several variables, including credit score, gender, and age.

This post discusses the classical Central Limit Theorem and demonstrates its usage through the Normal approximation of the Binomial distribution with a Shiny app.

This post discusses type I and type II errors, along with power. Basic background knowledge regarding hypothesis testing and $p$-values is assumed in this post.

This post explains the basics of hypothesis testing and provides a simple hypothetical pharmaceutical example of testing whether a new drug is better than an existing drug.

This post provides a complete walkthrough of analyzing Abalone data from Kaggle and applying supervised machine learning (ML) regression methods in R using the tidymodels package. The best model is selected from a suite of candidate models, including random forests and extreme gradient boosting (XGBoost).
