Objective Function Options for Model Fit Assessment

Default settings for objective function options in model fit analysis, pivotal for calculating error and fit. These configurations enable tailored analysis approaches, pivotal in the ParameterIdentification process for optimizing parameter values against observed data. These options are configured via the PIConfiguration class.

Usage

ObjectiveFunctionOptions

Format

An object of class list of length 6.

Details

Settings include:

objectiveFunctionType

"lsq" for least squares; influences error calculation.

residualWeightingMethod

"none" by default; specifies method for residual weighting.

robustMethod

"none" for standard analysis; selects method for robust outlier handling.

scaleVar

FALSE by default; determines if scaling is applied to residuals.

linScaleCV

0.2; coefficient of variation for linear scaling.

logScaleSD

NULL; standard deviation for log scaling.

These options are configurable in PIConfiguration, directly influencing the calculateCostMetrics functionality for detailed model fit assessment.
