Modellresultater

Modellresultater is a term used in Norwegian and Danish contexts to describe the outputs produced by applying a model to data. They summarize what the model implies about the world, and can include point estimates, probability distributions, predicted values, and results of simulations or scenario analyses. The nature of the results depends on the model type, the data input, and the assumptions built into the model.

In statistics and machine learning, modellresultater often comprise predicted values, confidence or credible intervals, and measures of predictive performance. In mechanistic or engineering models, they may include simulated trajectories, forecast profiles, and stress-test outcomes.

Validation: To assess usefulness, modellresultater are evaluated on independent data or through cross-validation, back-testing, or prospective testing. Common performance metrics include RMSE, MAE, R^2 for regression; accuracy, precision, recall, AUC for classification; calibration and Brier score for probabilistic forecasts.

Interpretation and communication: Reports describe the model structure, data sources, preprocessing steps, assumptions, and limitations. Uncertainty and domain validity are emphasized; results are presented with appropriate context and caveats.

Reproducibility and ethics: Best practices include sharing code and data where possible, recording versioning, seeds, and parameter settings. Considerations of bias, fairness, and potential harms are relevant when modellresultater inform decisions.

Applications: Modellresultater are used across disciplines such as economics, epidemiology, environmental science, engineering, and policy analysis to inform decisions, forecast demand, assess risk, and simulate outcomes under different scenarios.
