A Single Parameter Family Characterizing Probability Model Performance
Introduction We’ve been writing on the distribution density shapes expected for probability models in ROC (receiver operator characteristic) plots, double density plots, and normal/logit-normal densities frameworks. I thought I would re-approach the issue with a specific family of examples. Definitions Let’s define a “probability model” ...

R is Getting an Official Pipe Operator
It looks like R is getting an official pipe operator (ref). R doesn’t work under an RFC process, so we hear about these things and they are discussed on the R-devel mailing list. I’ve written on this topic before (ref), and I have taped some new comments. (link) My feeling is: argument inserting syntax translation is indeed a tempting way t...

My Opinion on R’s Upcoming Pipe
R‘s upcoming pipe appears to be currently proposed as a syntactic transform of the form: a |> f(...) -> f(a, ...) a |> f() -> f(a) There is a current active discussion on this prototype and some interesting points come up. Note the current proposal appears to disallow a |> f -> f(a), a currently popular transform. ...

Some Fun With User/Package Level Pipes/Anonymous-Functions
In addition to adding a base-R pipe it appears a new base-R function builders is in the works (in addition to “function”). R is a very versatile language, with a great ability to accept user-level or package extensions. What I mean by this is, user code and package code (which have about the same level of privilege) can control quite a lot. A...

Bounding Excess Generalization Error
I am sharing a new free video where I work through a great common argument that bounds expected excess generalization error as a ratio of model complexity (in rows) over training set size (again in rows), independent of problem dimension.
