Hey, I would consider attending. I have no particular thoughts to share. This year, I think I may wind up leading an initiative to develop a Shiny App for data exploration (e.g. Dose-PK, Dose-PD, PKPD, with continuous, binary, etc.). My vision is that we'd start small and gradually grow. So a

I wanted to follow up on the comments to Yaping's email.First, the three probabilities below from the original code do in fact sum to 1. P(1)=THETA(8)/100 P(2)=(1-THETA(8)/100)*THETA(9)/1000 P(3)=(1-THETA(8)/100)*(1-THETA(9)/1000) Note that: P(2) + P(3) = 1-THETA(8)/100 And

Hi, I'm trying to solve an indirect response model in Nonmem where the drug effect depends upon the dose, which can change every day. Currently, I'm using the ADVAN6 routine, but because I have thousands of time points for about a thousand patients, Nonmem is quite slow. I thought that in
