Model inputs
Five scientist-facing controls at most.
Compare a parameter
How does one model input change the response?
How do dose regimen and body size change pembrolizumab concentration and cumulative exposure?
exploratory clearance L day
Model parameter controlling exploratory clearance l day.
Exploratory range around the default value.
5 evenly spaced values in L/day. Other model inputs and the simulation window stay fixed.
Interpret with care
- Interpret trajectories as deterministic model behavior, not as a patient-specific prediction or dosing recommendation.
- Paper-result and exact-anchor checks remain in the private validation lane and are not part of this public scenario.
Review the server-confirmed fixed price before starting the comparison.
Comparative response
End-of-window response across the selected parameter values.
Choose an exploratory range around the default, review the fixed price, and run the comparison.
