Question: CI for transition intensities ratios #103

Closed iago-pssjd closed 1 month ago

iago-pssjd commented 1 month ago

Dear Prof. Jackson,

I have found at least a couple of papers where they show ratios of transition intensities with Confidence Intervals. See Table 3 of https://www.neurology.org/doi/10.1212/WNL.0000000000200051 or Table 2 of https://doi.org/10.1186/s12877-019-1291-z.

My question is which is the right way of computing those CI, if it is possible? I may try to divide the CI for the transition intensity in the numerator by the CI for the transition intensity in the denominator with the opposite order (so Lower/Upper and Upper/Lower), but is this correct? If not, is there another way?

Thank you in advance for your time!

I have just found the function qratio.msm. I'll keep the issue open, just ofr confirmation.

Thank you for the package and help.

That is the one. See the help page for how the CI calculation works here.
