Specify fitting compartment #560

Closed DimitrisVoul closed 2 years ago

DimitrisVoul commented 2 years ago

Hello, I have a dataset with multiple CMTs inlcuding absorption, central and effect. It was created to fit the data simultaneously with multiple endpoints bit now I only want to fit the data of the 3rd CMT which is the effect. When I write

effect ~ prop(effect.prop)

Where do I specify which DV data to use for the fitting (namely only the CMT=3 ones)

Hi @DimitrisVoul

In theory you can look at the multiple endpoints output. This is discussed here:

https://nlmixrdevelopment.github.io/nlmixr/articles/multiple-endpoints.html

The table tells what CMT or DVID values correspond to an effect.

If there is something unclear there, please let me know.

DimitrisVoul commented 2 years ago

Is that throught the command

nlmixr(Model)

because when I run it without multiple endpoints I don't get any infomation regarding the CMT or DVID

mattfidler commented 2 years ago

In that case, the evid is sufficient to model the data. If it doesnt work it is a bug.

Hello,

No I don't want to fit with multiple endpoints. I am only interested in fitting one of the CMT. How can I specify which CMT/DVID nlmixr uses to fit the data?
