Ever struggle with features in your data overshadowing others due to different scales? Normalization can be your hero!

In R, there are ways to transform your data for a more even playing field. This post explores two popular methods:

  1. Z-score normalization
  2. Min-max scaling

The map() function applies a function across vectors, lists, or data frames efficiently. Syntax: map(.x, .f, ...) where .x is data, .f is function, ... for extra args. Examples: square vector elements via ~.x^2, get means of column across list of data frames with ~mean(.x$y), apply custom functions to rows/cols like df$z <- map_dbl(df, add_cols).

@unusual_whales not surprising to see this as when capital accumulates it helps to write legislation to continue its greedy feeding

"What does it say about the US that Trump has minions behind him ready to put the infrastructure of authoritarianism in place, and legions of average citizens eager to see him break the traditions and handrails that once made America a model of democracy? I think it tells us that Trump’s rise is symbolic of a cultural breakdown that won’t be ameliorated by a single election."

tapply() in R is a powerful function for applying a specified function to subsets of data defined by one or more factors. It simplifies grouping and summarizing data, making it essential for data analysis tasks.

As data analysts, we know that no model is perfect. Residuals, the differences between observed and predicted values, offer valuable insights into the strengths and weaknesses of our models. Introducing the plot_regression_residuals() function from the tidyAML R package - a game-changer for visualizing regression residuals.

Google Podcasts is going away (because of course it is) and apparently I'm putting off the migration until the last minute 🙈

Can you share your fave podcasting app for Android? I don't need fancy, but I would prize a nice lock screen UI and easy queue management.
