AlgebraOfInference.jl

In early developments!

Provide unified algebra like syntax for hypthosis testing, inspired by AlgebraOfGraphics.jl and R package infer.

The goal of the package is to provide a new interface to HypothersisTest.jl and also a wrapper of testings from R via RCall.jl.

Features

• @formula expression support
• composable testing constructions

Quick Starts

Any data source that supports Tables.jl interface will work.

To run a test, first specify variable to be used in testing, and multiple specifications can be added together.

specs = specify(@formula(a ~ b)) + specify(:a, :c)

The same is hypothesis tests, theorectically, it should work with all tests from HypothesisTests.jl. Incorporate more tests.

tests = testwith(EqualVarianceTTest) + testwith(UnequalVarianceTTest)

Then, p-value can be calculated together:

tbl = (a = rand(100), b = repeat(1:2, inner = 50), c = rand(100))
test_specs = specs * tests
test_specs(tbl) .|> pvalue

Table outputs

Powered by SummaryTables.jl, the test outputs can be easily collected into one table:

test_specs(tbl) |> table

To-Dos

• Nicer printing
• Nice looking tabel outputs
• Optimize code
• Import test from R
• Refine interface
• Documentations
• More series testing
