Using yieldcurveml in Python examples for 'Beyond Nelson-Siegel and splines: A model- agnostic Machine Learning framework for discount curve calibration, interpolation and extrapolation'

      I have been at lots of business meetings where the speaker would say something like, "As the red line clearly demonstrates, ..."       I would quickly look up at two particular co-workers. ...

1 Introduction This article is part of a broader series on data preprocessing in R. In earlier posts, we focused on two problems that quietly ruin analyses long before modeling begins: missing data and outliers. Both topics shared a commo...

Testing Super Learner with TMLE showed some interesting patterns 🤔 XGBoost + random forest only hit ~54% coverage, but tuned xgboost + GLM reached ~90%. Seems like pairing flexible learners with stable (even misspecified) models helps? Need to explo...
