Did not get proper subject fits plots

1

Hi.
This is how my derived block look like.

  @derived begin
        ubp = @. Central/V2
        DV ~ @. Normal(ubp, ubp*(σ1_p))

        bp = @. Peripheral/ V3*pub
        BDV ~ @. Normal(bp,bp *(σ2_p))

        tc = @. (ubp + bp)
        PHNY ~ @. Normal(tc,tc*σ3_p)

    end

I tried to get subject fits using below code

f = subject_fits(res_inspect_fm ,
             separate = true, 
             paginate = true, 
             facet = (combinelabels = true, ), 
             figure = (fontsize = 18, ), 
             axis = (xlabel = "Time (hr)", 
                    ylabel = "conc", ))
        #     legend = (merge = true, unique = true))
f[1]

Fits gave below image

plot_1
plot_1800×600 21.1 KB

Can someone tell me where i went wrong ?

Thank you.

Did you check the result of DataFrame(inspectobject, include_covariates=false, include_events=false, include_icoefs=false) to see if you are getting predictions for all observations?
