Interactive visual learning

Model, equation, code, and curve—kept in sync

Change one parameter, predict the consequence, then compare the mechanism, formula, implementation, and curve. Values are theoretical teaching examples, not fitted clinical results.

Interactive theoretical model curveCurve updates with the selected parameter.

Correct versus misspecified diagnostics

Interpret first: Which panel shows a systematic model failure, what is the likely cause, and what targeted check should come next?

Adequate residual pattern
Misspecified residual pattern

Schematic diagnostic comparison. The time trend suggests missing dynamics or timing problems; first verify time, dose history, and study-specific data, then test a targeted structural remedy.

Dose → exposure → decision

Dose-regimen simulator

1-compartment teaching model

Try this: Keep the daily dose constant—compare 100 mg every 12 h with 200 mg every 24 h. Which regimen produces the smaller peak–trough swing?

Concentration over time after repeated dosesThe concentration curve is the sum of every administered dose. Markers identify dose times.

What the curve means

NONMEM event encoding

Deterministic one-compartment simulation for education. It demonstrates regimen mechanics and is not a patient-specific dose recommendation.
