Shaded cells represent conditions altered from baseline (status quo) scenario
1
Standard error estimates and approximations were calculated for each cell based on 38 simulations for each level of the parameters. All standard error estimates were less than .32%.
2
Standard errors were approximated using the Taylor series expansion which included variance terms for the baseline and alternative simulations.
3
Standard errors were calculated by pooling variance terms from the baseline and alternative simulations and assuming that they were equal.
