Introduction Over the next few minutes, I’ll send you on your way to leveraging linear regression for a bit more than explanation or prediction, rather you’ll utilize them to for the sake of inference. We will leverage simulation for inference in three ways: Understanding model sensitivityp-valueconfidence intervals In this post, we’ll mostly be exploring the […]

The Intuitive Explanation of Logistic Regression
Introduction Logistic regression can be pretty difficult to understand! As such I’ve put together a very intuitive explanation of the why, what, and how of logistic regression. We’ll start with some building blocks that should lend well to clearer understanding so hang in there! Through the course of the post, I hope to send you […]
Three Key Charts for Visualizing Proportion Data
Proportion data examples Whatever your application of data analytics & data science, there are proportions everywhere. Proportions are all about understanding the different parts that make up a whole. Proportions are pretty much just a count of something across a given categorical variable. That could be number of customers across different industries, number of sales […]

Principal Component Analysis in R
Hi there! Welcome to my blog on pricipal component analysis in R. Purpose: PCA is a dimensionality rediction technique; meaning that each additional variable you’re including in your modeling process represents a dimension. What does it do?: In terms of what PCA actually does, it takes a dataset with high dimensionality, and reduces them down […]
