Sensitivity analysis in excel helps us study the uncertainty in the output of the model with the changes in the input variables it primarily does stress testing of our modeled assumptions and leads to value-added insights. Definition: a sensitivity analysis is a mathematical formula used in financial modeling to calculate if a target variable is influenced by other outside variables called input variables. My question is about accounting for the uncertainty of material selection in sensitivity analysis (uncertainty importance) specifically, i want to know whether it matters (from a confidence in my results point of view) that the material is not perfectly known. Sensitivity analysis on an individual crop basis, tomatoes and potatoes were the most increasing, sensitivity analysis and scenarios suggest high variability and limited short-term impact on poverty alleviation.
The way i look at it is, we found these results, and even though our data are biased (mnar), our sensitivity analysis— which biases the results the way we think they are biased in real life—shows that our results don't change.
