Hi Kim-Anh,
Thank you very much for taking the time to respond to my inquiry, I sincerely appreciate it!
This makes sense, as I have only ever seen 95% CIs for VIPs obtained via jack-knife resampling. Perhaps that can be something to consider adding in future iterations? Just a thought!
And thank you for sharing this information on how the VIP is calculated. It is also very helpful to me.
All the best!
