I'm not clear on how to perform sensitivity analysis on the priors. Many sites have different answers. One site indicates to perform three non-informative, weakly informative and known priors. Another suggest running the model with different priors.
Here are my questions:
I want to estimate this parameter A, in which A = mean1 + mean2 . So, the priors for mean1 and mean2 are formulated (coding) as the following :
- mean1 ~ N(u1, tau1) mean2 ~ N(mean1, tau2)
where tau1 ~ gamma(alpha1,beta1) tau2 ~ gamma(alpha2,beta2).With the above formulation, how do I perform the sensitivity analysis ?
