Basics of Bayesian Attribution
This is a pretty simple implementation of a real client need; note that this was HIPAA-friendly at the time.
Machine Learning Resources, Practice and Research
Testing various ML methods
Code for a paper I wrote using non-parametric testing of Likert Scale data.
RF Interence Analysis
Robyn is an experimental, automated and open-sourced Marketing Mix Modeling (MMM) package from Facebook Marketing Science. It uses various machine learning techniques (Ridge regression, multi-objective evolutionary algorithm for hyperparameter optimisation, gradient-based optimisation for budget allocation etc.) to define media channel efficiency and effectivity, explore adstock rates and saturation curves. It's built for granular datasets with many independent variables and therefore especially suitable for digital and direct response advertisers with rich dataset.
SQL commands to create simple PostgreSQL DB
I created a RDMS with R and a front-end with Shiny. Depending on your setup you might have to reconfigure the shiny.r file.
