Herein, I will walk through a machine learning example from start to end and explain how to use the appropriate tidymodels packages at each place. For example, the user would call rand_forest instead of ranger::ranger or other specific packages. These questions were driven by the fact that when we started developing the workshop, using tidymodels required fairly advanced purrr skills; see an end-to-end code example from Max’s Applied Machine Learning workshop at rstudio::conf(2019) here.

One difficulty I am having is that I have not seen much documentation on how to use this framework for hyperparameter tuning. , HTML pages, presentation slides, PDF documents) starting with the same code base. This makes it easy to report results, create plots and consistently work with large numbers of models at once. Decouple the model specification from the implementation (whether the implementation is in R, spark, or something else). tidymodels have since then seen quite a bit of progress. tidymodels is more or less a restructuring of the caret package (as it aims to do the same thing and more) but with an interface and design philosophy that resembles the tidyverse. Is there a natural way to use model validation/interpretation packages like iml and DALEX? Are there some cookbook like examples comparing how some problems are solved with caret and tidymodels for side-by-side comparision?. Introduction This is a follow up post of using simple models to explain machine learning predictions. But this time, we'll focus on the uncertainty examples, especially on linear regression.

Clustered standard errors are popular and very easy to compute in some popular packages such as Stata, but how to compute them in R? With panel data it's generally wise to cluster on the dimension of the individual effect as both heteroskedasticity and autocorrellation are almost certain to exist in the residuals at the individual level. Statistical parameters for the steps can be estimated from an initial data set and then applied to other data sets. roles define how variables will be used in the model.
