I am currently working on my Bachelor´s Thesis and I therefor need to do some statistical work. I am analyzing the effects of Migration over time.
My hypothesis is that when two independent varbiables reach a certain level in one country, a third dependent variable decreases in that exact year. This requires as well that the dependent varibale is increasing before and after this specific threshold of the indipendent variables.
Is there a way to test this hypothesis using R?
Thanks in advance
