AchievementsCourse challenges and how many learners hold them
How to read this courseNotation, shared pages and conventions
Shared Probability Theory and Probability Distributions concepts have one canonical page here. Those pages keep both courses’ tags and source references, and the Probability Distributions homepage lists them in its weeks alongside its advanced topics.
A density is fixed only up to its values on a set of zero length (zero area for joint densities), for example at finitely many points: changing it there changes no probability. Identities between densities on these pages therefore hold except possibly on such a set.
