Impact of Budget Deficits on Treasury Yields with XGBoost
Charles Schwab analysts said that historically, budget deficits have had minimal impact on Treasury yields, primarily due to the United States’ economic dominance and its status as the issuer of the world’s reserve currency. The variable importance analysis with the XGBoost machine learning model confirms the aforementioned statement. Source ...
From Math to Code: Building GAM with Penalty Functions From Scratch
Enjoyed learning penalized GAM math. Built penalty matrices, optimized λ using GCV, and implement our own GAM function. Confusing? Yes! Rewarding? Oh yes!
We dove into the engine of what made basis spline work on our last blog, now let’s add to...

Investigating running R on RISC-V thanks to r-base on Ubuntu
Introduction
I was interested to see whether and how well R would run on the new RISC-V architecture.
A while ago I read that RISC-V is now a
first class architecture for Ubuntu.
This got me thinking, instead of having to build R from source maybe the...
