Continue reading →: Analytic Hierarchy Process (AHP) using preferenceFunction in ahp
Yesterday, I wrote about how to use gluc‘s new ahp package on a simple Tom-Dick-Harry one level decision making problem using Analytic Hierarchy Process (AHP). One of the cool things about that package is that in addition to specifying the pairwise comparisons directly using Saaty’s scale (below, from https://kristalaace2014.wordpress.com/2014/05/14/w12_al_vendor-evaluation/)… …you can…

Continue reading →: Analytic Hierarchy Process (AHP) with the ahp Package
On my December to-do list, I had “write an R package to make analytic hierarchy process (AHP) easier” — but fortunately gluc beat me to it, and saved me tons of time that I spent using AHP to do an actual research problem. First of all, thank you for writing…

Continue reading →: A Discrete Time Markov Chain (DTMC) SIR Model in RThere are many different techniques that be used to model physical, social, economic, and conceptual systems. The purpose of this post is to show how the Kermack-McKendrick (1927) formulation of the SIR Model for studying disease epidemics (where S stands for Susceptible, I stands for Infected, and R for Recovered) can be easily implemented…

The purpose of this post is…
Hello,
I’m Nicole
Since 2008, I’ve been sharing insights and expertise on Digital Transformation & Data Science for Performance Excellence here. As a CxO, I’ve helped orgs build empowered teams, robust programs, and elegant strategies bridging data, analytics, and artificial intelligence (AI)/machine learning (ML)… while building models in R and Python on the side. In 2025, I help leaders drive Quality-Driven Data & AI Strategies and navigate the complex market of data/AI vendors & professional services. Need help sifting through it all? Reach out to inquire – check out my new book that reveal the one thing EVERY organization has been neglecting – Data, Strategy, Culture & Power.
