In my previous post, I shared my annual running stats which were generated in R using summary data from Garmin Connect. The code I use to generate these summaries was beginning to get a bit unwieldy, so I have now rebased it into a package. GarminCSVr – is an R package ...

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. ...

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...
