 # Literature Review
 While in general I looked to sources that were thorough and gave results I could understand, there is little to be discussed in terms of scientific rigor/due-diligence in these sources. This is because it is generally incredibly clear if a method or calculation is correct, because it can be tested, as I have been doing very frequently throughout creating these models and during the test, it is clear if the change is having the expected effect. This is true in all the models except, perhaps, the machine learning. Where the model could implemented perfectly and we might still not see the expected results.
