Implement lasso regularized regression modeling in R using tidymodels and #TidyTuesday data on episodes of The Office. Explore the process of building a dataset, separating rows, creating a workflow, and performing lasso fit with grid functions. Visualize error bars, analyze variable importance, and reorder variables for optimal results. Test the model and draw conclusions from this practical application of machine learning techniques to analyze popular TV show data.
