rz is a series of classes and utility methods for applying statistics concepts through computation. In other words, while existing code is there for handling statistics-related work within R lang, this work composes:
- Composes said helper methods within modules.
- Makes these methods available while incorporating Object Oriented principles.
- And, in some cases, performs tests of said code.
Groups of functions have been grouped into centralized concepts with differentiation on two_sample_hypothesis_tests and one_sample_hypothesis_tests, and both normal_distributions and uniform_distributions. Find what you are looking for, plug in appropriate instance variables, and call an appropriate function.
If for whatever reason a function is not listed and one feels like it should be, they can search for it like so:
FuzzySearch("p-value", "/Users/user/Development/rz/src").search_for_string()
