1
State the central method of Parameter Estimation, Residuals & Model Comparison and list the conditions that must be checked.
Faculty solution: Use using data to estimate parameters and inspect model error. State the relevant hypotheses, domain or interval, units when applicable, and a verification plan.
2
Data follow y=y₀e^{kt}; explain a linearizing plot.
Faculty solution: Plot ln y versus t; slope estimates k and intercept estimates ln y₀.
A learner makes an error by ignoring initial conditions, step size, equilibria, or model residuals. Explain the first invalid step and repair the reasoning.
Faculty solution: The first invalid step is ignoring initial conditions, step size, equilibria, or model residuals. Return to the governing definition or theorem, restore the missing condition, and verify the corrected result.
5
Create a short application of Parameter Estimation, Residuals & Model Comparison in population, cooling, mixing, finance, medicine, circuits, and resource systems. Define variables and identify the quantity an integral, differential equation, sequence, or series would measure.
Faculty solution: A defensible response defines variables and units, states assumptions, builds the correct mathematical object, and interprets its value in population, cooling, mixing, finance, medicine, circuits, and resource systems.
6
Describe two independent ways to verify a result from Parameter Estimation, Residuals & Model Comparison.
Faculty solution: Use an exact structural check such as differentiation, substitution, partial sums, or theorem hypotheses; then compare with numerical, graphical, dimensional, or limiting evidence.
