Scm/equations

[JorgeLuizFranco]

Added basic retrieval equations from CausalGraph generated.

For now, the regression is pure OLS, but we can make improvements. Also, we assume the input for retrieving the equations a SimpleDigraph(est_g in the examples) and a DataFrame, and return the variables and the corresponding coefficients ( linear relationships assumption).

[JorgeLuizFranco]

Expect and check if it is a DAG. Get residual of OLS. x = coefficient[1] + scale[1]*randn(). Parameter ::AbstractMatrix use Tables.jl. SCM should also return the DAG.

A couple of todo's:

[ ] include the file in CausalInference.jl
[ ] figure out if you really need DataFrames, and if so, add it to the project
[ ] write a simple test making sure the code runs.

Done, Moritz

Ah great, that is taking shape.

1.) Can you uncommit the changes to the yaml files, why is a figure deleted?
2.) Include the test in runtest.jl

[JorgeLuizFranco]

I think everything now is as requested @mschauer
