9.4 Chapter summary

Sensitivity analysis is the investigation of the extent to which your conclusions depend on your analytic choices. There are often many reasonable specifications of your models, and you want to know to what extent they all point in the same direction. Specification curve analysis using package specr is a particularly systematic way of doing sensitivity analysis. Like related approaches such as multiverse analysis, specification curve analysis requires you to think of all of the ways you could have analysed the data.
