Non time-based model: sequence statement

Phoenix Certara Forums Modelling and Simulation

Hello,

If I have a non time-based multinomial PD model, for example:

covariate(Dose)

covariate(Time)

p(..) = ilogit(th1+E)

E = th2Dose(1-T)

will I be able to use a Sequence statement, say:

sequence{

T=1

sleep(4)

T=0

}

will this still result in T=1 for 4 time units and T=0 after that? is sleep statement associated with the Time from the “covariate”?

Thanks,

SL

Hi Sinyinlim,

it would be helpful if you could provide your example in form of a Phoenix project file. That would allow us to better understand the issue and provide help. If this is confidential, you may want to send your query to support@certara.com.

you can always have a fake ODE that would allow you to use some of the nice features of " time aware " models.

as Bernd mentioned without a complete model code and a better understanding of what you need we cannot help much.

Thanks for the comment.

It seems like having a deriv(Time = 1) works for me. I assumed that’s the “fake ODE”?
