This chart is the code's result. Run recomputes it in your browser.

Horizontal break against induced vertical break, one cloud per pitch type, contours of where each pitch lives. Pick a pitcher; hover for the averages.

Edit me: Change the sample size from 18 to 120 per pitch and run again, or add a column to the summary.

Who it is for

For people who want all of it.

The analyst building a body of work

You want the live rooms to ask questions in and the courses to go deep, across Python and R, models, apps and pipelines.

The engineer who ships

You want the production half: Shiny at scale, Docker, scheduled pipelines, and the AI tooling that now sits inside all of it.

The person changing fields

You know data from finance, engineering or medicine and want the current methods on data you care about; sport is the classroom, the methods travel.

Not for you if you want one topic only: buy that session or course on its own instead.

The lighter option

Live sessions only? The Masterclass.

Every live session for a year, with every recording, for $1,899 a year, or $199 a month (renews monthly at $199, cancel any time by replying to your receipt), or 3 monthly payments of $699. The courses are not included; Membership adds all of them.

Questions

The ones that stop a purchase.

What exactly is included?

Every live Masterclass session for a year with its recording, every self-paced course on the catalog, and the courses that are added while your membership runs.

Do I keep the recordings?

You can watch every recording and every course while your membership is active.

Is it a subscription?

Membership is an annual plan. You choose at checkout; a person answers any question about renewal before you buy.
