Many SEs and CIs of estimates have formulae and well understood properties For those that do not, we can bootstrap the SE of any estimate - e.g., the median Bootstrapped estimates (mean of simulated replicates) can be used to assess bias Bootstrapping is not a panacea - requires a good sample size t ...
